I used to have a huge collection of games. But I sold most of them off. There was a time where I had duplicates of a lot of the games I owned. I would use these games to trade or sell for other games I don't have. But, currently I don't have more than one copy of the games I currently own. Do you guys have any duplicates in your collection? What are your plans for the duplicates? Do you keep them? Trade/sell for other games?
