As ugly as the mii in that commercial is, I'm really [ixke]too[/ixke] excited about the Miis finally being playable in Smash bros. I mean, its pretty much a custom character creator and I'm coming into this prepared.

We got the Persona 4 cast here. From top left to the right: Kanji, Teddie, sassy Dojima, Nanako, Adachi, Yukiko, Naoto (sadly no blue hair or hat), Yosuke, Yu and Chie.

And a mixed group of characters here. Geno (Super Mario RPG), Hank Hill, Porky (Earthbound), Luke Fon Fabre and Guy Cecil (Tales of the Abyss), Master Chief (Halo), Tiz, Edea, Ringabel and Agnes (Bravely Default)[/spoilerxke]
I think even with the excellent roster we already have, expanding it with unrealistic characters is never a bad thing.
