The wider family LitRPG belongs to: stories shaped by games (a game world, quests, a dungeon run) where the numbers can be light or missing. Stores and publishers often file GameLit and LitRPG on the same shelf.
Soundbooth Theater files Everybody Loves Large Chests under "Fantasy, GameLit, Humor, LitRPG", and Podium labels its LitRPG audiobooks "LitRPG & Gamelit".
