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

[bananaking21]

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

 

Edit : for people who thought this was my own personal opinion

metacritic scores

littlebigplanet 95 > 89 super mario bros DS

Littlebigplanet 2 91 > 87 super mario bros Wii

Littlebigplanet vita 88 > 78 super mario bros 2 3DS
