Mario: Great
Zelda: Replace Toon Link with Ghirahim, and I like it.
Pokémon: Why two trainers? I'd rather see Zoroark.
DK: Great
Wii Fit: Duh.
Mother: Fine if you absolutely need a third rep.
Metroid: Great
Kid Icarus: Great
Animal Crossing: I'd love to play as Tom Nook, but I don't think AC should get two reps off the bat.
Wario: Great
Waluigi: Good
Sonic: Too much. WAY too much.
Kirby: It could use Waddle Dee.
Star Fox: I don't see him coming back, but better him than Ms. Bluetits.
Who's Wonder Red?
Bayonetta: Fine
Fire Emblem: Great
Pikmin: Great
ROB: I don't see him coming back.
Mega Man: Duh.
Zero: I don't see it.
G&W: Great
Ice Climber: Great
Xenoblade: Great
Its modtly good
Apart from too much sonic, Toon Link should be replaced, I'm iffy on Mother having 3 reps and I don't like the idea of two pokemon trainers.
Mario: Still rather have Toad, but that's fine I guess.
Zelda: Replace Skull Kid for Ghirahim
Pokemon: Don't care
DK: Fine
Yoshi: Fine
Earthbound: I doubt they will get another one. I mean, they're probably lucky they even got a second one. Remove Claus.
Metroid: Fine
Kid Icarus: Fine
Animal Crossing: I don't think they will add Tom Nook AND Villager. Probably safe to remove Tom Nook.
Wario: I don't know if Waluigi if gonna happen, but whatever.
Sonic: I don't think they are going to get another rep.
F-Zero: Fine
Kirby: Fine
Star Fox: Fine
Fire Emblem: Fine
Pikmin: Fine
Retro/Other: Mostly fine. Seems like you have a lot of third-party's though, and I don't think Mega Man will get another person (I think Zero is from that, I don't even know really).
