That's a pretty common complaint, since "going fast" and "glitchless" don't exactly go together and figuring out what even counts as a glitch is done on a game-by-game basis. Some games (a lot of RPGs for example, Pokémon games most notably) basically don't have an any% category anymore b/c glitching to the end just isn't as interesting as figuring out how to brave the random number generator.
