I just found my SNES! And, I played my first Zelda game! But that's the problem. I don't know any games to get. The games I have are as follows: Mario Paint,Mario All-Stars,Super Mario Kart,Battleship,F-Zero,Donkey Kong Contry, Super Mario World 1&2, Paperboy 2, Super game boy, and a few others. But what new games should I get?

Man, I wish I found an old SNES instead of buying one off of Amazon.

As for getting a new game, you have plenty, but how about the original Paperboy and Star Fox. Paperboy is probably at least similar to the arcade version (which I love), and Star Fox uses the best of Mode 7.

And Pie reminded me (wait, Yoshi said it as well, but I saw it on Pie's post first ), also Super Metroid. With the SSBB demo, I've gotten past the first level, and I like it so far.

Donkey Kong Country 2 and 3
Earthbound (good luck finding one cheap)
Kirby Superstar
Rock n' Roll Racing (plays similar to RC Pro AM)
StarFox
Super Mario RPG
Super Mario World 2: Yoshi's Island
Super Metroid
Tetris Attack

You should get the other Donkey Kong Country games. Donkey Kong Country 2 is the best of the three, and though Donkey Kong Country 3 is a bit easy it's still nearly as enjoyable as the other two. Oh, and the Kirby games for the SNES. Kirby's Dream Land 3 was just about my favorite game when I was younger. And Super Metroid is awesomely amazingly awesome. I didn't just say that so Lite wouldn't hurt me. It and A Link to the Past are the best games for the system.
Oh, and I had a lot of fun with Uniracers. :3

Ironically, I grew up playing Super Metroid. xD I completely recommend it.

There are hundreds of copies still in circulation, so finding one shouldn't be hard.

Other classics include Dungeon Master [Personal Favorite], Gauntlet, Super Contra, Arcana, B.O.B., and of course, Earthworm Jim.

Honestly, I just have a half-gig flash drive soldered to a gored SNES cartridge with full ROM and save state data capabilities. ROM without computer. :3
