Think back to the times before you had your own money. Back when you had to depend on mom and dad to sate your gaming needs. Every once in awhile, you may have come up with a game that you didn't like/ want. Or maybe there was a game you wanted at the store that you didn't have the cash for. Either way, in order to make up the cash, you sold or traded a game or two. But then, you began to get that empty sad feeling after doing so. For me, this was back in the early days of the PS1. I had traded my copy of Tekken or a copy of Doom. I have to say I almost IMMEDIATELY regretted that decision. And from that point on, I've NEVER sold back or traded a game ever again.
