LitRPG, short for Literary Role Playing Game, is a literary genre combining the conventions of computer RPGs with science-fiction and fantasy novels. The term is a neologism introduced in 2013. The proponents of the term state that in LitRPG, games or game-like challenges form an essential part of the story, and visible RPG statistics (for example strength, intelligence, damage) are a significant part of the reading experience. This distinguishes the genre from novels that tie in with a game, e.g. those set in the world of Dungeons and Dragons, or books that are actual games, such as the choose-your-own-path Fighting Fantasy type of publication. Typically, the main character in a LitRPG novel is consciously interacting with the game or game-like world and attempting to progress within it.
If the main characters are transported to a game-like world from our world, or can remember the real world, the genre can overlap with Isekai.
The literary trope of getting inside a computer game is not new. Larry Niven and Steven Barnes's Dream Park (1981) has a setting of LARP-like games as a kind of reality TV in the future (2051); Andre Norton's Quag Keep (1978) enters the world of the characters of a D&D game. With the rise of MMORPGs in the 1990s came science fiction novels that utilised virtual game worlds for their plots. Early examples are Tad Williams' 1996 - 2004 tetralogy, Otherland, Conor Kostick's 2004, Epic and Charles Stross's 2007 Halting State. In Taiwan, the first of Yu Wo's nine ½ Prince (½ 王子 Èrfēnzhīyī Wángzǐ) novels appeared, published in October 2004 by Ming Significant Cultural. In Japan, the genre has reached the mainstream with the release of the media phenomenon Sword Art Online in 2009. Also of note is the Korean Legendary Moonlight Sculptor series with over 50 volumes.
While these novels and others were precursors to a more stat-heavy form of novel, which is LitRPG proper, a Russian publishing initiative identified the genre and gave it a name. The first Russian novel in this style appeared in 2012 at the Russian self-publishing website samizdat.ru, the novel: Господство клана Неспящих (Clan Dominance: The Sleepless Ones) by Dem Mikhailov set in the fictional sword and sorcery game world of Valdira, printed by Leningrad Publishers later that year under the title Господство кланов (The Rule of the Clans) in the series Современный фантастический боевик (Modern Fantastic Action Novel) and translated into English as The Way of the Clan as a Kindle book in 2015. In 2013, EKSMO, Russia's major publishing house, started its multiple-author project entitled LitRPG. According to Magic Dome Books, a major translator of Russian LitRPG, the term "LitRPG" was coined in late 2013 during a brainstorming session between writer Vasily Mahanenko, EKSMO's science fiction editor Dmitry Malkin and fellow LitRPG series editor and author Alex Bobl. Since 2014, EKSMO has been running LitRPG competitions and publishing the winning stories.
Many of the post-2014 writers in this field insist that depiction of a character's in-game progression must be part of the definition of LitRPG, leading to the emergence of the term GameLit to embrace stories set in a game universe, but which don't necessarily embody leveling and skill raising. One of the earliest examples is Chris Van Allsburg's Jumanji, a children's book about a magical board game.
Although released in 2011, Ernest Cline's novel Ready Player One which depicts a virtual reality world called OASIS filled with arcade references from the 80s and 90s, became an example of this new genre. Other examples include Mary Lu's 2017 novel Warcross which is about an online bounty hunter in an internet game, and Louis Bulaong's 2020 book Escapist Dream which tells the story of a virtual reality world where geeks can role-play and use the powers of their favorite comic book, anime, movie and video game characters.
