I know a few but I want to know what you guys think are the best genesis games?

Paper Mario for the N64 is a must have. The gameplay is awesome. If you like Thousand Year Door you are going to love the original paper mario.

I LOVE the original GB games and play them alot! I LOVE donkey kong land it rules another game I play in my original GB is the original pokemon series! I would never give away my GB games!
