Age of Empires II Tips

Defeat yourself
If you want to defeat yourself, but don't want to use one of the other "losing" cheats (like "resign",) just start a regicide game, type "natural wonders" in the chat box, hit enter, and then use an animal (like a boar, wolf, or jaguar) to kill "your" king (which you will have lost control of) just like you kill an enemy unit.

Note: Natural Wonders is a cheat to lose control of your other people and switch to controlling animals. If you click the technology tree button, though, it will cause the game to crash. I sen a report on this to Apple...
