Yep, I always find it a bit odd when I complain about something in CoD and then someone will inevitably come back with a 'RoF is great though - play that instead!'.
It's as if I said I needed help with my moguls skiing and the advice came back 'Try backgammon.. - it's great!!!' .
I guess they are all just games, and that they are all flight sims, but if I wasn't specifically interested in the WWII stuff then I wouldn't have been interested in CoD.
