For those who don't trade in your games.

[Cloudman]

I keep my games and almost never sell them back. I stupidly and tragically sold many of my N64 games to get another system, and now I miss those games that I sold, and they are expensive/rare to get back. : ( So after that, I decided never to sell them again. I do go back and play old games when I have the chance, even if it`s sparse. It`s easier to get back to games you own vs. finding the game you once played but want to play again.
