Not a problem. I just put in my closet or something. I will probably end up playing it though. I don't sell any of my games anymore though (I think the last time I sold or traded in a game was like 4 years ago).
Same here. I've regretted losing every game I've sold. Even if it wasn't very good, I get the urge to try them again from time to time and some of them would have been great for potential RetroActives.
Off the top of my head I've sold:
Command & Conquer 64
Dark Summit (GC)
Resident Evil 2 (N64)
Turok 2 (N64)
Harvest Moon: It's a Wonderful Life (GC)
Rogue Squadreon 2 (GC)
More NES games that I care to think about...

The only one I don't regret selling is the GC Harvest Moon. I really didn't like that game. The others I've wanted to try again at some point. I've sold others, but can't recall them right now. Intrestingly, I know I've never sold off an SNES game. Rather proud of that
