My list looks like that :

1. BEST GAME OF ALL TIME : GOD OF WAR I & II (no game is as good as those 2, cant wait for GOW3! Seriously try it if u havent Xbox360 grafics u can have those on PS2 with that game. Some Genious coded the games.)
2.Final Fantasy Series (especially FF12 and all oldskool NES and SNES)
3.Zelda A link to the past (played through like 1xxxxxx times) / Zelda Twilight princess (but on Gamecube cause Wii remote sux )
