I recently came across a neat indie game, called 0 A.D.. It is an RTS game featuring real historical societies from 500 B.C. to 500 A.D., and best of all, it is (or rather, will be) totally free! The game is currently in it's Alpha stage. As a bit of a history nut, I like the detail the folks at Wildfire Games are putting into this, and it looks like it won't be just your average strategy game. Heroes from the various societies are available as Super Units (including Leonidas, Julius Caesar, Hannibal, Xerxes, and others), and each society has a whole new playing style, and isn't just a sort of retextured copy of the others. And what cool societies! They are going to include the Greeks, the Romans, the Persians, and a lot more! I may seem a little overzealous in my promotion of this game, but it looks awesome and nobody I know has heard of it, so I'm trying to spread the word. Anyways, enjoy this little bit of info.
