I disagree with you on the overall quality of SSE, BP, but I certainly see your point. It's interesting to imagine what Brawl might have been had less time been dedicated to the single-player modes. But even so, I'm really satisfied with the Brawl that we got. SSE has its flaws, but I had loads of fun with it. I even liked the Great Maze! And multiplayer also has flaws, but they aren't flaws that, to me at least, make it unfun. That said, I'm really interested to see where Smash 4 goes, both in terms of multiplayer mechanics, and whatever single-player modes it ends up with. I'll probably even end up buying it twice!
