"marco polo" to reveal the whole map in Age of Empires 2 - you had to enter "marco" and then "polo" but not together, and "lumberjack" to get free wood, there were a lot more but I don't remember

You never tried the "how do you turn this on"? I think this is the best cheat available in the game. 

Is that the one that makes some car appear?
