The most historically accurate games

Can we here collect the most historically accurate games? (Strategy, RTS, etc.) The ones which inform us about history of humanity.

I love Sid Meier’s Civilization type of games. however while they have some historical accuracy the format of these games do mot allow to narrow down into too much details as they include many different civilizations and long timeframes.

What games do you have on your mind that you could recommend for its historical and informative value?
