Favorite 2D Super Mario Game on a Home Console

[Sorcery]

Super Mario World for me. Although I prefer the style of Super Mario Bros. 3 the most, the game simply doesn't challenge me enough, whereas SMW does (to an extent). NSMBWii is cool, but it doesn't stack up against SMW or SMB3 at all.

So yeah, SMW, I love it. I just wish that it had half the style of SMB3.
