We still have our NES and we have games like Final Fantasy, Swords and Serpents, Bucky O'Hare, Battletoads, two copies of Legend of Zelda, Mario 1 and 3, Kirby, and a bunch of weird tactics games. I haven't gotten it out in years, but it was always a lot of fun. And I had the magic touch for getting it to work. My brother an friends never could. Oh, and Blades of Steel?
We have an SNES but not many games. Donkey Kong Country, Act Raiser, Gradius III, Super R-Type, Tetris Attack (so fun to play competitively when drunk), Super Mario World, of course. There were some others, like an SD Gundam Super Famicom game that was modified to fit in our SNES, and a few sports games. I always wanted a copy of Chrono Trigger for it, but I never found any. (It's all right, though, since I have it on PS1 and I have the DS version and the SNES emulator).
As for PS1, I have all the Final Fantasy games except VII, I have a kinda scratched copy of Wild Arms, Chrono Cross, and several more I don't ever play anymore.
I have two GameCubes, but Paper Mario and the Thousand Year Door and Super Smash Bros. are the only games I have for them. I have a modded original XBox and only two games for it. D&D Heroes and Star Wars Battlefront II. Still have Pokemon Blue, Link's Awakening DX (the one for GameBoy Color) and a few others, as well as a small collection of GameBoy Advance games, like the second Golden Sun, Sword? Of Mana, Pokemon Leaf Green and Ruby, and some others.
I dunno if we're counting PS2, but I have a bunch of those games still, too. Shadow Hearts 1 and 2 are my favorites.
