I included COD4 as an option to some people for Conan Exiles, but from my experience traders don't want to part with their Conan copy no matter what I come up with. Sorry to delay my answer again, but Conan is the game I want the most this year, so I am still hoping. Will definitely let you know today how it turns out and won't trade COD4 with anyone else. :)
if you buy the new monthly i could get you conan for cod 4 + mutant year zero
conan is pretty pretty expensive
