I don't think the "random matches" should be a category at all. there is too much variance in the skill of players of both the person running, their teammates ad the opponents they would fight. it's also pretty usual to not include (online) competitive matches as a part of speedrunning.
though i would also extend this to get ride of the "cpu matches" category as there is still lots of variance even with computers opponents, i would like to hear thoughts on just ridding of "random matches"
Seeing as it is 100% i feel like getting all the costumes would be a part of it. the Feats of Glory could be a maybe because they act as the achievements and i don't know if other 100% runs in other games count the achievements.
The costumes would also, probably, just turn into grinding money for a bit to get them all.
For IRL, do the pencils have to start as unsharpened? Because it says so in the rules but, i think, the top 3 places for 1 pencil start with partially sharpened ones.
