Lol. Did Sony really "push" those games though? Sure they sold well - but Sony's marketing wasn't all that great. I remember Sackboy being really big back in 08/09 and comparison to Mario was made all the time. It's pretty obvious why the character didn't take off; it's because the franchise never took off. The franchise never took off because Sony didn't "push" it. 5 games in 5 years? Mario has almost double that in one year alone (you can check back in the 90's and the number still holds true).
In summary: Lack of marketing; not enough games.
