Well Medal Of Honor really started the FPS (First Person Shooter) war genre, so basically Call Of Duty copied the concept and made it more realistic and enhanced graphics and such. Medal Of Honor has stayed with the same concept so far and really can't do to much without copying Call Of Duty. Airborne was good, but not as good as Call Of Duty 4 in my opinion. Don't expect to much out of Medal Of Honor though...they might surprise us with the next one.
I have always been a big fan of CoD. I only played MoH once, and that was a really old one. I don't really like the older CoD games, although yeh war games, being set in WW2 is just boring to me, that's why I liked the Modern Warfare game, and can't wait for Modern Warfare 2
