Almost every game has a 100% speedrun category, and i think this could be really interesting to this game too. Maybe it is kind of boring to grind kills to get the item switch, but still we can show skills in dominate every character to do so. Absolutely something i would run.
All Unlocks is a meme category that nobody runs mostly because of 30 minutes of non-stop match resetting. You literally start the match, pause-reset, and repeat 100 times. And this is for 30 minutes straight. My PB/WR for this is something like 1h55m, so over 25% of the run is match resetting pretty much.
The other issue with "All Unlocks" is some requirements are completely arbitrary. You do one run on Normal, then 7 runs on Very Easy, using the original 8 characters. You don't do runs of the unlockable characters at all.
The "100%" category that does exist is pretty much "All Characters X Difficulty". You do a classic run using every character in a given difficulty. IMO it's essentially the "100%" category, and doesn't have any random arbitrary or 30 minute grinding moments.
Alright i get it, just a little thing: i think if you're doing a "100% run" you should also play with the unlockable characters as well. And also i don't think the resetting part could be something to don't include it, because this category exist also in super mario odyssey, which has more time of the run getting coins to unlock everything.
The "All Characters X Difficulty" does use all 12 characters. You do a classic mode run of all 12 classic characters back to back, with your time ending when you finish the last character.
Unless you meant something else.
