[Super Buu]

Play Metroid Fusion. I did that, then went out and actually bought it (again, if you know what I mean) because the damn thing was so good. Thus began my long-running obsession with the series. Zero Mission and Super Metroidz are also good, but my favourite 2D Metroid is Fusion, blasphemous as that may be to purists.

Aside from that, Donkey Kong Country series, Comix Zone (try to beat it. Go on, try), Ristar ... uh, I'll try and think of more.
