In my dreams i see a mission where i can observe mission territory and enemy and learn their routines and from that knowlage i can make plans for my actions and movements, ofcourse then mission objectives must be set that way so they can be completed better if player takes time to make this kind of plans.
Maybe 10 years ago or so there was some aircraft show near my hometown and with my friend we wanted to go to that show but we didnt have money for the tickets so we planed to make our way to there sectretly. We had to go through small willage that was occupied with protect service persons, they patrolled on all small gravel roads so we waited to patroll turn away and go other direction and then we could advance to next position that we used to hide, we used all possible places to move un detected, old buildings, tree lines and bushes to make our way through, it was exiting and fun and we succeeded and got to the show
That kind of mission would be fun to play
