It's got enough WarioWare juice that this was gonna be a good time no matter what, but I do think the gimmick of different character playstyles, while impressive in its variety, does hurt the general conceit that you should be able to figure out each microgame immediately as soon as you start it. It's a lot harder to do that when the character you end up with has to complete the game entirely differently from everyone else and/or is completely unsuited for said microgame anyways.

Also, maybe just a personal brain issue but it really bugged me that there were separate achievements for player-selected rosters vs. all characters, would've just preferred the latter personally. The character-specific achievements were a nice touch, though.
