I was thinking about this for an idea but what if we had a game where you raced every mushroom cup,every flower cup, every star cup, every special cup, then for the games that have it, every shell cup and so on.

While we could have categories for multi-game runs, I'm not sure whether speedrun.com currently has a way to handle them properly. Either way, if multi-game categories were to exist, they most likely wouldn't be individual cups per game, but rather multiple full-game runs (such as SMK/MK64/MKDD as a "Classic Trilogy" category or MKSC/MKDS/MK7 as a "Handheld" category, for example).

They have the multiple Mario games which hold the SM64,SMS,SMG,SMG2 back to back runs. it's just the overall time

Now why would you post that on this thread instead of making your own thread?
