I know what he's saying im 15 and have aquired 1000 games over the last year. ive seriously thought about selling all the ones i dont play regularly,but i havent really had time to play a game in 6 months with the football season staring and the regular weight lifting. another reason i havent sold mine is because ive sold some of my non gaming collections and a few months later i was kicking myself in the ass.
But anyway... do what you feel is right, Goodluck with your sale.
