Doesn't let me vote on anything now for some reason, but it goes:
1) SSB4
2) Melee
3) Project M
4) N64
5) Brawl
It's not as if I've played Project M, but I watch quite a bit of it. Brawl is fine, but the competitive aspect just doesn't belong in that game.
SSB4 Main - Pikachu, and pretty good one at that. I was called the best Jigglypuff player too by a Pro Mario player. Pockets - Mario, Peach
Melee Main - Jigglypuff, upthrow + rest. Pockets - Fox, Marth
Project M Main - None
N64 - Fox, even though I can't get used to his lasers being different in this game. Pockets - Don't have any
Brawl Main - Zelda, I don't play competitive Brawl so I just spam side special. Pockets - I don't play competitive Brawl, but it'd be Marth.
