Yeah, I keep them all. You never know when you'll get that urge to play old games, which is why I keep them around. I remember selling most of my N64 games to get a PS2, and I still regret it to this day. Since then, I don't sell my games any longer... unless I absolutely don't care about a game. The only console I got rid of was the GC, since there was no need for it after getting a Wii.
