how are price's on ebay for game's like super mario 3D land zelda oot 3D star fox 64 3D resident evil mercenaries or the other one that's name i can't spell
Nintendo first party games (like the first 3 on your list) are usually hard to find for cheap, but the two Resident Evil games are always less than 20 bucks these days on Amazon. I imagine Ebay has similar prices.
If you like fighting games, Super Street Fighter 4 is one you can find for cheap these days. Usually goes for around $15.
Theatrhythm Final Fantasy is the 3DS game with my most play time. After the DLC it isn't that cheap, but it sure is a hell of a lot of fun. I always go back to it!
Kid Icarus is also good fun, and makes me laugh with the dialog.
Devil Survivor Overclocked is awesome and very long.
Tales of the Abyss is pretty great and long, but sometimes I feel like a lot of the parts of the game is "Go here to see scene, okay. Now, go over to this part of the world. Excellent. Now, back to where you started! Perfect! Okay, we might open up this next dungeon if you go talk to this person on this side of the world..." Kinda annoying, but overall it was a good game.
