I've been speedrunning the Super Mario 64: Sonic Edition Romhack, and it's a ton of fun. Playing the game with the Sonic Adventure moveset is an interesting challenge, making alot of thing trivial but, also making others more difficult. I've been having a ton of fun. But, of course nobody else is running that romhack, so it's been tough pushing myself without any competition. But, I'm looking to meet more people interested in this run and maybe even getting it's own category someday!
