the time changes, cod 2to 4 had to be perfected because of lack of fastpatching, cod1 was their first step. when cod 5 arrived, it had its problems and was being patched and patched. Same with MW2 but IW had more reputation with call of duty series, and had more glitches(note that release date was given almost year before its release and didn't then had even storyline completed...
