I've bought and played every "Smash" game for hours on end. As much as I LOVE the series, I'm hesitant to buy a Wii-U just to play it. I know I'd do terrible on a 3DS (I NEED a controller to play that game, all there is to it) so I won't bother with that version..
Favorite Fighters: Pit (no, I'm not a bow spammer!), Link, Capn' Falcon Punch, DeDeDe, Zelda (Princess forme) and Marth (Ike was fun too, but easy mode).
Truth be told though, I purchased the Gamecube AND Wii SPECIFICALLY to play Smash games (I bought the N64 for Ocarina of Time though xD), so it's still a possibility I'll be hyped into it. >_<
