NASCRAG is the National Society of Crazed Gamers, a group of game-masters, writers, and artists who have been presenting a series of multi-round Dungeons and Dragons tournaments at the Gen Con game convention since 1980.
The NASCRAG tournament is one of the largest and the oldest independent role-playing competitions at Gen Con. It is a three-round, single-elimination, team advancement tournament in which teams of six (this number has varied over the years) compete with other teams by playing a D&D adventure. Teams are scored on role-playing, and achieving personal and team goals.
NASCRAG is an independent gaming organization that consists of a core of 60 to 80 members (along with a number who have become less active over the years). GenCon provides Nascrag with 20-30 complimentary GM badges every year and some judges simply pay their own way. Being well staffed allows NASCRAG to accept many walk-up participants and to give players two game masters for all the NPC action in Round 3.
NASCRAG is run by "Squirrel Queen" Carole Bland. Carole took over the post from her husband, NASCRAG Chief Lackey Emeritus, Len Bland, in the 1990s.
Since 2004, the job of marshaling the roughly 100 players per timeslot (4 or 5 timeslots per year) into manageable teams of six is handled by NASCRAG's Master of Ceremonies Tom Lommel and his assistant Buster Pishkur. Through many years in the 1980s and 1990s, Buster also assisted NASCRAG's longtime Head Marshall "Big" Al Baker.
NASCRAG's elaborate scorekeeping system is currently handled by Jim Carter.
In 1979 a group of friends attending Gen Con wanted to play in the D&D Open. But the Open was very popular and had to turn away many players that year. These friends, headed up by Len Bland and James Robert, decided to run their own tournament starting in 1980.
Bill "Indy" Cavalier joined the group in 1982 and has been contributing an increasing number of illustrations to NASCRAG events ever since. Indy's lighthearted style complements NASCRAG's humorous adventures.
After more than two decades of existence, NASCRAG and its players have formed a growing community at Gen Con. Hundreds of players return every year to play and try to win. Some teams have been participating for decades.
NASCRAG sometimes draws on this pool of experienced players to refresh the ranks of their judges. At other times, NASCRAG has found other sources of quality judges. No matter the source - NASCRAG's goal is to maintain high-quality staff.
NASCRAG has been around long enough that several children of the original members now judge for the group.
Early NASCRAG adventures featured intricate story lines with epic heroic adventure and puzzle solving. This has evolved into an emphasis on role-playing, humor, and puzzles that differs greatly from the combat, strategy, and dice-rolling of traditional D&D tournaments. The NASCRAG focus is on the characters, their interactions, and their relationship to the unfolding story. The characters are individually illustrated and often given distinctive mannerisms or vocal accents to encourage role-playing.
Every year, NASCRAG runs a multi-round adventure as its primary tournament.
