• 0 A.D. was originally based off of Age of Empires II and is a /great/ alternative to the series. It includes many advanced features and multiplayer support, and is completely open source! How much better can you get? (0 A.D. is currently in alpha development, so there a a couple of bugs and a few features are missing, but it is still very playable and fun.)

The fact that it is open source means also: infinitely better mod support, constant improvements to AI and other aspects of the game. Also free and easy to install and to play multiplayer.
