GameLit
The broader umbrella of game-influenced fiction, with or without explicit tracked mechanics.
GameLit is the broader umbrella genre for fiction influenced by games: it uses game elements as backdrop or flavor, with or without an explicitly tracked mechanical system. Genre reference material frames LitRPG and GameLit as overlapping, complementary labels rather than a strict subset relationship, and some works carry both.
The practical distinction for a writer choosing tags: if the system's numbers are load-bearing (the reader must see them for the story to work), you are writing LitRPG; if the game framing is atmosphere, GameLit fits.
