You should come play some more Duke! NoTargets made some excellent co-ops and I really liked the one you made with all the zero's and the P38's. I love flying that plane!
the problem I think is its not somthing you can pick and play, it takes patience and some dedication and the planes are all very different so you pick one, learn it and then move on to another although there some if you learn them you can fly anything else. Its like going in at the deepend. Its painful to start with but the rewards are better.
However its an incredible game and the nice thing is you learn allot of history while playing it, especially from the original. I've learnt allot about the former USSR though it, more than I did at school.
I'll go on about this game all day so I'll stop now but heres my baby:
