How about the ability to swim or use scuba gear. Aircraft carriers where jets and helos could land and take off from and be boarded from small boats. Better urban comabt scenes with all buildings open and able to be used and communities that make sense such as have grocery stores, gas stations, movie theaters, etc. AI that picks up ammo when their out instead of just saying their low on ammo. Also, have AI when on the same side go to each others defense even if they have to break out of a waypoint pattern to do so instead of just going to the next spot while someone else right beside them who isn't in their group gets dropped by enemy fire. Overall the game is the best I've yet to play and I hope that OFP2 will surpass it!
