hope these arent too stupid but how about
1. a second korean war obviously set in modern or very near future times
b. a POW rescue mission that is like coop or multiplayer that the players are both the rescue team and the pows, i realize for the pows it would be boring but it might be an interesting change, and once you free ya gotta fight your way out so.....it wont be all boring
5. grenada or panama maybe?
