Grottos & Gremlins is a role-playing game of some sort, and is most likely a parody of real world games such as Dungeons & Dragons, Magic: The Gathering, Warhammer, and other games of the sort. It involves role-play, miniature strategy, collectible cards, a board, and character sheets. The Nerds are avid fans of the game, and are seen playing it in the cafeteria during cutscenes, and often talk about it. Rockstar had planned to integrate Grottos & Gremlins as a minigame, but the idea was scrapped due to a lack of time.
