0 A.D. is a free, open-source, cross-platform real-time strategy (RTS) game of ancient warfare. In short, it is a historically-based war/economy game that allows players to relive or rewrite the history of Western civilizations, focusing on the years between 500 B.C. and 500 A.D.











































































The game was made as the successor to Lord of Ultima. This is the perfect alternative. Almost exact same gameplay. Would highly recommend.
