Why did Sony go with Super Smash Bros. too instead of Super Mario Bros. too?

its because Sony has a superior 2D platforming game, its called littlebigplanet

How can anyone compare LBP with a game like SMB3? It's something totally insane, because LBP has not nearly the same quality, is a franchise much younger, and infinitely less sold. Just because Sony copy the games and gives upgraded features and modernized does not mean they are better.

It's really laughable.
