For those who don't trade in your games.

I don't know how much I have.... but as long as I still have the device to play them on the chance of me going back exists. I went back to mk DS not too long ago I'll go back to Pokemon HG now and again (same with kirby superstart ultra) and even though I'll never play some games again I just like to keep them around to remind me of my playthrough. I'd only ever trade in games if I really desperately needed money.
