I don't automatically think of online gaming when I think of Smash Bros. though. If they nerfed the multiplayer aspect of it somehow, then I'd be a lot more disposed to rage then if they didn't release a complex online system.
They haven't given us a complex online mode, BUT that's not the main focus of the game. Never has been. Therefore, I say 'Meh' to the online mode. I can take it or leave it.
