which game are you playing call of duty 4, call of duty 5, or the conduit

I had Conduit but sold it because it was a pretty big letdown and I heard a lot of people started hacking in online matches. COD4 I use to play on 360, now I play MW2. I don't really care about World at War, there are two many WW2 shooters as it is.
