Picture the scene:
You buy a new Tom-Clancy type game for your XBox / PS2 / PC and rush home to play it. You guide your soldier through the enemy terrain and discover an enemy outpost ... which then surrenders. Hmmnn ... pressing on you come across more enemy, they all surrender too. The 'enemy' people welcome you with open arms and you are declared victor and given a high score.
What would you do?
You'd take it straight back to the shop saying it was totally unrealistic crap!
unless ...
... it is a war-game for the pentagon - in which case you base a whole military campaign on it, commit hundreds of thouands of troops and billions of dollars to it.
Maybe I'm being a little unkind but this does seem to be the gist of it !
