I eventually get rid of virtually all my console games. I've still got loads of PC games, mainly because they're much harder to get any money for - because most shops won't take them.
The only possible 'keepers' would be the Resident Evil remake, Res Evil Zero & Res Evil 4 for the Gamecube. I've only got a few 360 games at the moment - TDU, GoW, Dead Rising, Madden, Just Cause, CoD3 and Oblivion. I may hang onto TDU & Oblivion from those.
