Well, honestly, not much....many of my games have been lost (via my younger brother), or borrowed and not returned. What remains is Tecmo Super Bowl, Mario Bros/Duck Hunt, Tecmo NBA Basketball, RBI Baseball, Donkey Kong, and a couple of others I can't remember off hand right now (nothing great). Some games I thought were fun that my friends had but I never did were: Kid Icarus, Mega Man, Metroid, Mike Tyson's Punch Out, Pro Wrestling (had, but lost somehow), Zelda, Excitebike, etc. I've also thought about looking for the Empire Strikes Back game (remembered renting that one), as well as Super Dodgeball, which I've heard is a lot of fun.
