Yeah, that's fair. I guess I'm just speaking for myself on this one, but I think an all characters run would be a ton of fun due to all the 1P modes you have to dabble with, and having a sub-optimal time as a result of wanting to do that over SDing for X hours is an honest mood killer

I think this is a cool base idea, but mewtwo makes it awkward. My Question would be can we leave the game idle until we can fight mewtwo, and then restart the game. The timer starts, and we enter into a single 1 stock match, beat him, and then do everyone else normally?
Also I think this would need to exclude "play X vs matches" unlocks because trying to SD as fast as possible for X hours doesn't make for an interesting run

You can also pick charizard before fighting Petey and have the same kind of affect, but idk what the time save on it actually is.

I've been trying to think about a way to do target test, since that's always been one of my favorite things. Since there's only 5 levels, a normal run would be too short for my tastes, but since there's 36 characters, to do a run of "1 level all characters" would be too long (god forbid all levels all characters)

I know Melee has a player who does a lot of HRC on his stream, and he's done HRC speedruns at smash the records' events before where the run was to get a cumulative 100,000 ft, or something along those lines. That could be adapted to brawl for sure as well
