(Putting this here because ideally, Wario would be in it too) Both these series always seemed to be somewhat similar in many ways. They've always had quite a steady character-base, and would possibly work well together. But... What kind of game would it be though? A platformer may make it seem really disjointed, but it can still be an adventure of both series coming together. Maybe a whole different genre, though? But what... And after we've figured that out, what other characters from both series would there be in it?
