It's called bullshit.
Reality is if it is possible to running around in the town with a map in my hand. If I crash into a wall or a tree than it is my own fault!
Please dont talk about reality. Is it reality when a infantrie soldier can drive and fly al kinds of vehicles??? Is it reality when every soldier can look on a map and see his position and the positions from other soldiers? Like the Marauders Map in Harry Potter???
Or crash with a motorcycle in a tree with 90 km/h and after that I say AUTSCH and continue by running? Or is it realistic to bee shoot in your leg, then you crouch to a first aid tent and heal yourself?
Reality is ok. But you need a kind of balance in the game between reality and fun!
