Well I didn't see this anywhere so here we go. I've been playing the Wii U version of SSB and so far I'm loving it, Brawl is still my favorite cause of the Story Mode but I like Wii U just as much since it's thing are the Amiibo figures. Anyway I'll list my favorite stages and characters.

Stages:

Fountain of Dreams (Melee/Brawl).

Big Blue (Melee/Brawl).

Bridge of Eldin (Brawl/Wii U).

Delfino Plaza (Brawl/Wii U).

Brinstar (Melee/Brawl).

Norfair (Brawl/Wii U).

More when I think of then.

Characters:

Link.

Zelda.

Peach.

Ganondorf.

Captain Falcon.

Samus and Zero Suit Samus.

Lucina.

Lady Palutena.

Kirby.

Luigi.

I play on the 3DS as a Marth main, but I also play Bowser Cap. Falcon and Jiggly Puff.
