0 A.D.

0 A.D. is a cross-platform, open source real-time strategy game centered on ancient warfare. It is for players who want strategy gameplay in an ancient military setting. It also suits people who need a game that runs on more than one computing platform. In real-time play, the action keeps moving instead of waiting through fixed turns. Players make strategy choices as that action continues. Its open source status also makes it useful to people who look for games with available source code. The game's scope is clear and focused on ancient warfare. That focus may be a limitation for players who want a broad range of eras or a different type of game. Cross-platform support is another point to check, since the term does not promise support for every operating system. Players should confirm that 0 A.D. runs on their platform before they install it.
