Don't you just hate that? When you sell a couple of games and then regret it some time later on.
My problem is not selling my games. I have tons. I'm just the type of person that goes back to play some of them even if I know I don't like them (ex: Sonic Unleashed). Even games that weren't big sellers and that I have gotten 100% on I go back to such as 'The Bourne Conspiracy'. I really need to sell some though but I feel like I will be in your situation if I do.
