if we make a flow chart we notice that the DCS simulator does not have a very specific purpose.
DCS: the pilot's plane starts from inside the plane (there is neither a guest house nor a briefing room.) Takes off, carries out the mission and returns to the base. If the driver is shot down in mission (kia Mia etc.) he dies and everything ends. if he ejects he survives and lands in a place on the map while remaining on foot but cannot return to base. RESULT = game does not give you a longevity because it does not stimulate you to continue. in DCS this game and open circuit system opens and then wins stop. if, on the other hand, you have a closed circuit and you return home safe and sound, the game has a closed circuit has an exact purpose and gives you more stimulus to play.
