I NEVER trade in or sell my games (unless I hated them). I still have all my N64, GameCube, Wii, Gameboy and DS games and ill be keeping my WiiU, 3DS and PS3 games too. I love having collections and like another poster said sometimes you really want to play the older game again and the way you did before. Plus Nintendo's first party games are too awesome, there genuinely is no reason I'd want to no longer have them.
