0 A.D. is a free, open-source, cross-platform real-time strategy (RTS) game of ancient warfare. It's a historically-based war/economy game that allows players to relive or rewrite the history of six ancient Western civilizations, from Iberia to Persia, each depicted at their peak of economic growth and military prowess. Developed using Pyrogenesis, a ground-breaking new game engine custom-built to suit this project, 0 A.D. will give players a rich and entertaining real-time gaming experience.
And finally here we have the finished result of the Persian Merchant, which EmjeR showed in his time-elapsed movie. This is a render made with the blender engine, so this is not the in-game look.
