A big ass pool of characters?Probably check
60 Frames per Second?Awesome check
A good Online Mode > SUPER AWESOME CHECK
The biggest thing that annoys me with the SMB Series is the bad Online service from Nintendo
It will probably be a lot easier with the Sony Smash Game.
And there is always the possibility of DLC Characters.Sony needs to talk with SquareEnix and stuff to get Cloud and so on cause they are more or less Sony Exclusives too.
