I keep most, but once in a while I'll go through and sell a few. Eusis, now that you mention it, I should sell Metroid: Other M... that was a dissapointing game, but I doubt I'll get much for it. Games I don't like, I sell. But I find some value in most of the games I play. I sold Dragon Age though, along with some others. I'll probably sell New Vegas. There's a number I will probably never play again, it's probably time I went through and weeded things out.
