It's funny you created this thread. Just today I went through this big stack of games I got during the holiday season (most on BF). I decided that 4 of them I didn't even want to play so I'm reselling them on eBay to try to get my money back. I have limited gaming time and I don't want to spend it on games that I don't have a lot of interest in playing.
While I haven't lost all interest in games like you have, I have gone through my games and backlog a lot lately and cut TONS of stuff out and got rid of it. Going forward I'll try to stick with the best games that I want to play.
