To be honest, this is a really bad game battle. On one hand, you have smg which has a superior single player and is only singleplayer. On the other, you have SSBB with superb multiplayer, something smg doesn't have. And SSBB doesn't have a singleplayer experience as excellent as SMG. But also keep in mind that SMG is also a platformer while SSBB is a fighter. Both of these are totally different games, it's the same as comparing apples to oranges where the only way they are related is that they are fruit and have seeds.
