In the recent(ish) movie Midway there is a scene where the IJN is wargaming the upcoming attack, and they get their asses kicked since some cheeky junior officer playing the Americans doesn't keep the carriers waiting in Pearl Harbor but rather NE of Midway (which is what later happened in reality). So they reprimand that officer and restart the game with the clause that the US carriers must stay at Pearl until the attack on Midway island starts.
Don't know whether such a wargaming episode happened in reality.
