The best part of this game will always be Subspace Emissary and the Demo's for games each fighter originates from. I spent countless hours playing demo's for games I'd never even heard of as a kid and I've lost track of the number of times I've played Subspace with my brother and best friend. Also the art style in this game is one of my favourites in the Smash series. I'm heartbroken we never got a Subspace in Ultimate, otherwise it would have truly been the ultimate Smash for me.
