There isn't much story to Ultimate's single player mode. It's purely gameplay focused. It's going to be quite different to Subspace, and in fact is not connected to Subspace in any way.I know this -might- seem like a stupid question but is it recommended to watch the cutscenes from Subspace Emmisary before going into this Smash? I'm kinda a newcomer and it seemed like that was the last story-mode for Smash.
