Super Mario World - 'nuff said
Mario Kart - 'nuff said too
Zelda a link to the past : of course !
Secret of Mana / Secret of Evermore : boy i spent hours on those games, not only me, but my sister too and our mom liked to watch us playing and give us advices.
Final Fantasy IV : simply one of the best J-RPG ever written, and I'm not really a fan of FF generally
Super Probotector (european name for Contra 3, I think) : damn hard, damn impressive, damn good.
Donkey Kong Country 1-3 : amazing games, amazing graphics for the time.
Goof Troop: an excellent puzzle and reflexion game
