Ok, I thought that maybe after you beat SSE, that you could play it again, yet from the point of view from the villains. You would probably start off as Wario going to the arena, capturing one of the princesses. You could fight against bosses on the good guy side. It would be interesting to see the story from their side, see why they conquer other universes, and why the villains joined the subspace army. This might be asking to much from Sakurai's team though, it would be nice to see it happen.
