Is there any place I can go to get an estimate of what the value is of the games I have? I don't have a whole lot like some on here but all of my games include the box, instructions and everything inside. I feel like I should keep them, I don't play them but they are my childhood, but if I can make a few bucks, might be worth it. Just don't know what value to put on them or where to go to sell them.
