1) Super Mario Galaxy
2) Super Mario World
3) Super Mario Sunshine
4) Super Mario 64
5) Super Mario Bros. 2 (USA) [no, this is not a joke. ]
Regarding 3/4...I could go either way on those. Mario Sunshine has loooooads of flaws, but it's still lots of fun. Mario 64 is probably the better game, but its effing HORRIBLE camera controls knocks it down a notch. Especially now that we have 3D Mario games whose cameras don't make you want to bash your head through the TV.
