most educational computer game

[gaussianum]

 Although one usually makes a clear-cut distinction between games and simulators, I'll treat them as one on this subject.

 The best games for:

 Learning aerodynamics: Flight Simulator

 Learning WWII history: Hearts of Iron

 Learning Military Tactics: Panzer General

 Learning World History: Europa Universalis

 They are very educational, in a general sense. But not a replacement for a book on the respective subjects, of course.In my humble opinion.
