Nights into Dreams...[a] is a 1996 action game developed by Sonic Team and published by Sega for the Sega Saturn. The story follows teenagers Claris and Elliot, who enter Nightopia, a dream world where all dreams take place. With the help of Nights, an exiled "Nightmaren", they begin a journey to stop the evil ruler Wizeman from destroying Nightopia and consequently the real world. Players control Nights flying through Claris and Elliot's dreams to gather enough energy to defeat Wizeman and save Nightopia. The game is presented in 3D and imposes time limits on every level, in which the player must accumulate points to proceed.
Development began after the release of Sonic & Knuckles in 1994, although the concept originated during the development of Sonic the Hedgehog 2 two years prior. Development was led by Sonic Team veterans Yuji Naka, Naoto Ohshima, and Takashi Iizuka. Naka began the project with the main idea revolving around flight, and Ohshima designed the character Nights to resemble an angel that could fly like a bird. Ohshima designed Nights as an androgynous character. The team conducted research on dreaming and REM sleep, and was influenced by the works and theories of psychoanalysts Carl Jung and Sigmund Freud. An analogue controller, the Saturn 3D controller, was designed alongside the game and included with some retail copies.
Nights into Dreams received acclaim for its graphics, gameplay, soundtrack, and atmosphere. It has appeared on several lists of the greatest games of all time. An abbreviated Christmas-themed version, Christmas Nights, was released in December 1996. The game was ported to the PlayStation 2 in 2008 in Japan and a high-definition version was released worldwide for PlayStation 3, Xbox 360, and Windows in 2012. A sequel, Nights: Journey of Dreams, was released for the Wii in 2007.
Nights into Dreams is split into seven levels, referred to as "Dreams". The levels are distributed between the two teenage characters: three are unique to Claris, three to Elliot, and each play through an identical final seventh level, "Twin Seeds". Initially, only Claris' "Spring Valley" and Elliot's "Splash Garden" levels are available, and successful completion of one of these unlocks the next level in that character's path. Previously completed stages may be revisited to improve the player's high scores; a grade between A and F is given to the player upon completion, but a "C" grade (or better) in all the selected character's levels must be achieved to unlock the relevant "Twin Seeds" stage for that character. Points are accumulated depending on how fast the player completes a level, and extra points are awarded when the player flies through rings.
Each level is split up into four "Mares" set in Nightopia and a boss fight which takes place in Nightmare. In each level, players initially control Claris or Elliot, who immediately have their Ideyas (spherical objects that contain emotions) of hope, wisdom, intelligence and purity stolen from them by Wizeman's minions, leaving behind only their Ideya of courage. The goal of each Mare is to recover one of the stolen Ideya by collecting 20 blue chips and delivering them to the cage holding the Ideyas, which overloads and releases the orb it holds. If the player walks around the landscape for too long, they are pursued by a sentient alarm clock which awakens the character and end the level if it comes into contact with the player. The majority of the gameplay centres on flying sequences, which are triggered by walking into the Ideya Palace near the start of each level so that the character merges with the imprisoned Nights. Once the flying sequence is initiated, the time limit begins.
In the flying sections, the player controls Nights' flight along a predetermined route through each Mare, resembling that of a 2D platformer. The player has only a limited period of time available before Nights falls to the ground and transforms back into Claris or Elliot, and each collision with an enemy subtracts five seconds from the time remaining. The player's time is replenished each time they return an Ideya to the Ideya Palace. While flying, Nights can use a "Drill Dash" to travel faster, as well as defeat certain reverie enemies scattered throughout the level. Grabbing onto certain enemies causes Nights to spin around, which launches both Nights and the enemy in the direction the boost was initiated. Various acrobatic manoeuvres can be performed, including the "Paraloop", whereby flying around in a complete circle and connecting the trail of stars left in Nights' wake causes any items within the loop to be attracted towards Nights. The game features a combo system known as "Linking", whereby actions such as collecting items and flying through rings are worth more points when performed in quick succession. Power-ups may be gained by flying through several predetermined rings, indicated by a bonus barrel. The power-ups include a speed boost, point multiplier and an air pocket.
The player receives a grade based on their score at the end of each Mare, and an overall grade for the level after clearing all four Mares. Nights is then transported to Nightmare for a boss fight against one of Wizeman's "Level Two" Nightmarens. Each boss fight has a time limit, and the game ends if the player runs out of time during the battle. Upon winning the boss fight, the player is awarded a score multiplier based on how quickly the boss was defeated, which is then applied to the score earned in the Nightopia section to produce the player's final score for that Dream. The game also features a multiplayer mode, which allows two players to battle each other by using a splitscreen. One player controls Nights, whereas the other controls Reala. The winner is determined by the first player to defeat the other, which is accomplished by hitting or paralooping the other player three times.
The game features an artificial life system known as "A-Life", which involves entities called Nightopians and keeps track of their moods. It is possible to have them mate with other Nightopians, which creates hybrids known as "Superpians". The more the game is played, the more inhabitants appear, and environmental features and aesthetics change. The A-Life system features an evolving music engine, allowing tempo, pitch, and melody to alter depending on the state of Nightopians within the level. The feature runs from the Sega Saturn's internal clock, which alters features in the A-Life system depending on the time.
Every night, all human dreams are played out in Nightopia and Nightmare, the two parts of the dream world. In Nightopia, distinct aspects of dreamers' personalities are represented by luminous coloured spheres known as "Ideya". The evil ruler of Nightmare, Wizeman the Wicked, is stealing this dream energy from sleeping visitors in order to gather power and take control of Nightopia and eventually the real world. To achieve this, he creates five beings called "Nightmaren": jester-like, flight-capable beings, which include Jackle, Clawz, Gulpo, Gillwing and Puffy as well as many minor maren. He also creates two "Level One" Nightmaren: Nights and Reala. However, Nights rebels against Wizeman's plans, and is punished by being imprisoned inside an Ideya palace, a container for dreamers' Ideya.
One day, Elliot Edwards and Claris Sinclair, two teenagers from the city of Twin Seeds, go through failures. Elliot is a basketball player who enjoys a game with his friends. He is challenged by a group of older school students and suffers a humiliating defeat on the court. Claris is a talented singer and her ambition is to perform on stage. She auditions for a part in the events commemorating the centenary of the city of Twin Seeds. Standing in front of the judges, she is overcome by stage fright and does not perform well, which causes her to lose all hopes of getting the role. When they go to sleep that night, both Elliot and Claris suffer nightmares that replay the events. They escape into Nightopia and find that they both possess the rare Red Ideya of Courage, the only type that Wizeman cannot steal.
Once in Nightopia, they discover and release Nights, who tells them about dreams and Wizeman and his plans; the three begin a journey to stop Wizeman and restore peace to Nightopia. When they defeat Wizeman and Reala, peace is returned to Nightopia and the world of Nightmare is suppressed. The next day, back in Twin Seeds, a centenary ceremony begins. Elliot is seen walking through the parade until he has a vision of Nights looking at him through a billboard. Realizing that Claris is performing in a hall, Elliot runs through the crowd and sees Claris on stage in front of a large audience, singing well. The two look at each other, and are transitioned to a spring valley in Nightopia, which leaves ambiguity as to whether what they achieved was real or just a dream.
The concept for Nights originated during the development of Sonic the Hedgehog 2 in 1992, but development did not begin until after the release of Sonic & Knuckles in late 1994. Programming began in April 1995 and total development spanned six months. The development team consisted of staff who worked on previous Sonic the Hedgehog games: Yuji Naka was lead programmer and producer, while Naoto Ohshima and Takashi Iizuka were director and lead designer, respectively. Naka and Ohshima felt they had spent enough time with the Sonic franchise and were eager to work on new concepts. According to Naka, the initial development team consisted of seven people, and grew to 20 as programmers arrived.
Sonic the Hedgehog creator and project director Ohshima created the character of Nights based on his inspirations from travelling around Europe and western Asia. He came to the conclusion that the character should resemble an angel and fly like a bird. Naka originally intended to make Nights into Dreams a slow-paced game, but as development progressed the gameplay pace gradually increased, in similar vein to Sonic games. The initial concept envisioned the flying character in a rendered 2D sprite art, with side-scrolling features similar to Sonic the Hedgehog. The team were hesitant to switch the game from 2D to 3D, as Naka was sceptical that appealing characters could be created with polygons, in contrast to traditional pixel sprites, which Sonic Team's designers found "more expressive". According to Izuka, the game design and story took two years to finalise. The game's difficulty was designed with the intent that young and inexperienced players would be able to complete the game, while more experienced players would be compelled by the replay value.
The game was developed using Silicon Graphics workstations for graphical designs and Sega Saturn emulators running on Hewlett-Packard machines for programming. There were problems during early stages of development because of a lack of games to use as reference; the team had to redesign the Spring Valley level numerous times and build "everything from scratch". The team used the Sega Graphics Library operating system, said by many developers to make programming for the Saturn dramatically easier, only sparingly, instead creating the game almost entirely with custom libraries. Because the Sonic Team offices did not include soundproof studios, team members recorded sound effects at night. According to Naka, every phrase in the game has a meaning; for example, "abayo" is Japanese slang for "goodbye". The team felt that the global market would be less resistant to a game featuring full 3D CGI cut scenes than 2D anime. Norihiro Nishiyama, the designer of the in-game movies, felt that the 3D cutscenes were a good method to show the different concepts of dreaming and waking up. Naka said that the movies incorporate realism to make it more difficult for the player to disambiguate the boundary between dreams and reality.
The development took longer than expected because of the team's inexperience with Saturn hardware and uncertainty about using the full 560 megabyte space on the CD-ROM. The team initially thought that the game would consume around 100 megabytes of data, and at one point considered releasing it on two separate discs. Iizuka said that the most difficult part of development was finding a way of handling the "contradiction" of using 2D sidescroller controls in a fully 3D game. Naka limited the game's flying mechanic to "invisible 2D tracks" because early beta testing revealed that the game was too difficult to play in full 3D. The standard Saturn gamepad was found to be insufficient to control Nights in flight, so the team developed the Saturn analog controller to be used with the game. It took about six months to develop, and the team went through a large number of ideas for alternate controllers, including one shaped like a Nights doll.
Iizuka said that the game was inspired by Japanese animes and Cirque du Soleil's Mystère theatrical performance. The development team researched dream sequences and REM sleep, including the works of the psychoanalysts Carl Jung, Sigmund Freud and Friedrich Holtz. Iizuka analysed Jung's theories of dream archetypes and spent a considerable amount of time studying dreams and theories associated with them. Naka said that the main protagonist, Nights, is reflective of Jung's analytical "shadow" theory, whereas the two central characters, Claris and Elliot, were inspired by Jung's animus and anima.
Nights into Dreams was introduced alongside an optional gamepad, the Saturn 3D controller, included with some copies of the game. It features an analogue stick and analogue triggers designed specifically for the game to make movement easier. Sonic Team noted the successful twinning of the Nintendo 64 controller with Super Mario 64 (1996), and realised that the default Saturn controller was better suited to arcade games than Nights into Dreams. During development, director Steven Spielberg visited the Sonic Team studio and became the first person outside the team to play the game. Naka asked him to use an experimental version of the Saturn 3D controller, and it was jokingly referred to as the "Spielberg controller" throughout development. The game was marketed with a budget of $10 million, which included television and print advertisements in the United States. In the US, the game was advertised with the slogan "Prepare to fly."
Christmas Nights (クリスマスナイツ Kurisumasu Naitsu), or Christmas NiGHTS into Dreams..., is a Christmas-themed two-level game of Nights into Dreams that was released in December 1996. It was introduced in Japan as part of a Christmas Sega Saturn bundle; elsewhere it was given away with the purchase of Saturn games such as Daytona USA Championship Circuit Edition (1996) or issues of Sega Saturn Magazine and Next Generation Magazine. In the United Kingdom, Christmas Nights was not included with the Sega Saturn Magazine until December 1997. In a 2007 interview, Iizuka stated that Christmas Nights was created to increase Saturn console sales. Development began in July 1996 and took three to four months, according to Naka.
Christmas Nights follows Elliot and Claris during the holiday season following their adventures with Nights. Realizing that the Christmas Star is missing from the Twin Seeds Christmas tree, the pair travel to Nightopia to find it, where they reunite with Nights and retrieve the Christmas Star from Gillwing's lair.
Christmas Nights contains the full version of Claris' Spring Valley dream level from Nights into Dreams, playable as both Claris and Elliot. The Saturn's internal clock changes elements according to the date and time: December activates "Christmas Nights" mode, replacing item boxes with Christmas presents, greenery with snow and gumdrops, rings with wreaths, and Ideya captures with Christmas trees; Nightopians wear elf costumes, and the music is replaced with a rendition of "Jingle Bells" and an a cappella version of the Nights theme song. During the "Winter Nights" period, the Spring Valley weather changes according to the hour. Other changes apply on New Year's Day; on April Fool's Day, Reala replaces Nights as the playable character.
The game features several unlockable bonuses, such as being able to play the game's soundtrack, observe the status of the A-life system, experiment with the game's music mixer, time attack one Mare, or play as Sega's mascot Sonic the Hedgehog in the minigame Sonic the Hedgehog: Into Dreams. Sonic may only play through Spring Valley on foot, and must defeat the boss: an inflatable Dr. Robotnik. The music is a remixed version of "Final Fever", the final boss battle music from the Japanese and European version of Sonic CD (1993). In the HD version of Nights, the Christmas Nights content is playable after the game has been cleared once.
A game with the working title "Air Nights" was prototyped for the Saturn and began development for the Dreamcast, and in an August 1999 interview Yuji Naka confirmed that a sequel was in development; by December 2000, however, the project had been cancelled. Naka expressed reluctance to develop a sequel, but subsequently noted that he was interested in using Nights into Dreams as a licence "to reinforce Sega's identity". Aside from a handheld electronic game released by Tiger Electronics and small minigames featured in several Sega games, no full sequel was released for a Sega console.
On 1 April 2007, a sequel called Nights: Journey of Dreams was officially announced for the Wii. The game was first previewed on Portuguese publication Maxi Consolas, after the release of short reveals from the Official Nintendo Magazine and Game Reactor. The sequel is a Wii exclusive, making use of the Wii Remote. The gameplay involves the use of various masks, and features a multiplayer mode for two players in addition to Nintendo Wi-Fi Connection online functions. The game was developed by Sega Studio USA, with Iizuka, one of the designers of the original game, serving as producer. It was released in Japan and the United States in December 2007, and in Europe and Australia on 18 January 2008.
In 2010, Iizuka said that he would be interested in making a third Nights into Dreams game, should the management of Sega decide to commission one.
Nights into Dreams has an average score of 89 percent at GameRankings, based on an aggregate of nine reviews. In Japan, Nights into Dreams was the bestselling Saturn game and the 21st-bestselling game of 1996.
The graphics and flight mechanics were the most praised aspects. Tom Guise from Computer and Video Games heralded the game's flight system and freedom as captivating and stated that Nights into Dreams is the "perfect evolution" of a Sonic game. Scary Larry of GamePro said flying using the analogue joystick "is a breeze" and that the gameplay is fun, enjoyable, and impressive. He gave it a 4.5 out of 5 for graphics and a 5 out of 5 in every other category (sound, control, and FunFactor). Entertainment Weekly said its "graceful acrobatic stunts" offer "a more compelling sensation of soaring than most flight simulators". Edge praised the game's analogue controller and called the levels "well-designed and graphically unrivaled", but the reviewer expressed disappointment in the limited level count compared to Super Mario 64, and suggested that Nights seemed to prioritise technical achievements and Saturn selling points over gameplay with as clear a focus as Sonic. Martin Robinson from Eurogamer opined that the flight mechanics were a "giddy thrill". Colin Ferris from Game Revolution praised the graphics and speed of the game as breathtaking and awe-inspiring, concluding that it offered the best qualities of the fifth-generation machines. GameFan praised the combination of "lush graphics, amazing music, and totally unique gameplay". Next Generation criticised the speed, saying that the only disappointing aspect was the way "it all rushes by so fast". However, the magazine praised the two-player mode and the innovative method of grading the player once they completed a level. Electronic Gaming Monthly's four reviewers were impressed with both the technical aspects and style of the graphics, and said the levels are great fun to explore, though they expressed disappointment that the game was not genuinely 3D and said it did not manage to surpass Super Mario 64.
Levi Buchanan from IGN believed that the console "was not built to handle Nights" due to the game occasionally clipping and warping, though he admitted that the graphics were "pretty darn good". A reviewer from Mean Machines Sega praised the game's vibrant colours and detailed textures, and described its animation as being "fluid as water". The reviewer also noted occasional pop-in and glitching during the game. Rad Automatic from the British Sega Saturn Magazine praised the visuals and colour scheme as rich in both texture and detail, while suggesting that Nights into Dreams is "one of the most captivating games the Saturn has witnessed yet." Next Generation similarly commended the game's visuals, stating that they were "beyond a doubt" the most fluid and satisfying for any game on any system. Upon release, the Japanese Sega Saturn Magazine opined that the game would have a significant impact on the video game industry, particularly that in the action game genre. The reviewer also stated that the game felt better through the use of the analogue pad, in contrast to the conventional controller, and also praised the light and smooth feeling the analogue pad portrayed during gameplay.
Reviewers also praised the game's soundtrack and audio effects. Paul Davies from Computer and Video Games cited the game as having "the best music ever"; in the same review, Tom Guise attributed the music to creating a hypnotically magical atmosphere. Ferris stated that the music and sound effects were that of a dream world, and asserted that they were fitting for a game like Nights into Dreams. IGN's Buchanan praised the game's soundtrack, stating that each stage's soundtrack is "quite good" and that the sound effects "fit in perfectly with the dream universe".
In Electronic Gaming Monthly's "Best of '96" awards, Nights Into Dreams was a runner-up for Flying Game of the Year (behind Pilotwings 64), Nights was a runner-up for Coolest Mascot (behind Mario), and the Saturn analog controller, which the magazine called the "Nights Controller", won Best Peripheral.
Since its release, Nights into Dreams has appeared on several best game of all time lists. In a January 2000 poll by Computer and Video Games, readers placed the game 15th on their "100 Greatest Games" list, directly behind Super Mario 64. IGN ranked the game as the 94th best game of all time in their "Top 100 Games" list in 2007, and in 2008, Levi Buchanan ranked it fourth in his list of the top 10 Sega Saturn games. Next Generation ranked the game 25th in its list of the "100 Greatest Games of All Time" in their September 1996 issue (i.e. one month before they actually reviewed the game, and roughly two months before it saw release outside Japan). 1UP ranked the game third in its "Top Ten Cult Classics" list. In 2014, GamesRadar listed Nights into Dreams as the best Sega Saturn game of all time, stating that the game "tapped into a new kind of platform gameplay for its era".
Sega released a remake of Nights into Dreams for the PlayStation 2 exclusively in Japan on 21 February 2008. It includes 16:9 wide screen support, an illustration gallery and features the ability to play the game in classic Saturn graphics. The game was also featured in a bundle named the Nightopia Dream Pack, which includes a reprint of a picture book that was released in Japan alongside the original Saturn game. A Nights into Dreams handheld electronic game was released by Tiger Electronics in 1997, and a port of it was later released for Tiger's unsuccessful R-Zone console.
A high definition remaster of the PlayStation 2 version was released for PlayStation Network on 2 October 2012 and for Xbox Live Arcade on 5 October 2012. A Windows version was released via Steam on 17 December 2012, with online score leaderboards and the option to play with enhanced graphics or with the original Saturn graphics. The HD version also includes Christmas Nights, but the two-player mode and Sonic the Hedgehog level were removed.
In other media
Claris and Eliot make a cameo appearance in Sonic Team's Burning Rangers (1998), with both Claris and Eliot sending the Rangers emails thanking them for their help. Nights into Dreams-themed pinball areas feature in Sonic Adventure (1998) and Sonic Pinball Party (2003), with soundtrack being featured in the latter game. The PlayStation 2 games EyeToy: Play (2003) and Sega SuperStars (2004) both feature minigames based on Nights into Dreams, in which Nights is controlled using the player's body. Nights is also an unlockable character in Sonic Riders (2006) and Sonic Riders: Zero Gravity (2008).
A minigame version of Nights into Dreams is playable through using the Nintendo GameCube – Game Boy Advance link cable connectivity with Phantasy Star Online Episode I & II (2000) and Billy Hatcher and the Giant Egg (2003). Following a successful fan campaign by a Nights into Dreams fansite, the character Nights was integrated into Sonic & Sega All-Stars Racing (2010) as a traffic guard. Nights and Reala also appear as playable characters in Sega Superstars Tennis (2008) and Sonic & All-Stars Racing Transformed (2012), the latter of which also features a Nights into Dreams-themed racetrack. The limited Deadly Six edition of Sonic Lost World (2013) features a Nights into Dreams-inspired stage, "Nightmare Zone", as downloadable content.
In February 1998, Archie Comics adapted Nights into Dreams into a three-issue comic book miniseries to test whether a Nights comic would sell well in North America. The first miniseries was loosely based on the game, with Nights identified as male despite the character's androgynous design. The company later released a second three-issue miniseries, continuing the story of the first, but the series did not gain enough sales to warrant an ongoing series. It was later added to a list of guest franchises featured in Archie Comics' Worlds Unite crossover between its Sonic the Hedgehog and Mega Man comics.

Like the way Spielberg likes E.T. so much he won't remake it, I don't want to make another Nights. As soon as we realised this, we stopped making it... Yes, we made it up to a certain point. You know linear sensors? Well we made this system where you could remove the cable from the original pad and control Nights... it was called Air Nights.
