Good lord, I tried to rank my top 10 SNES games, and I'm amazed at how hard it is to do:
1) Super Metroid
2) Super Mario RPG
3) Mega Man X
4) Mega Man X2
5) The Legend of Zelda: A Link to the Past
6) Donkey Kong Country 2
7) Kirby's Dream Land 3
8) Kirby Super Star
9) Chrono Trigger
10) Super Mario World 2
On this list, I somehow had to leave off SMW, DKC, FFV and FFVI, Contra III, and Secret of Mana, plus a lot of other good games. Holy crap, the SNES is just so goddamn good.
