>What is 0 A.D.?
0 A.D. is a free as in freedom, open source game, inspired by Age of Empires 2. It's avaible for Windows, OSx, GNU/Linux and BSD
>Why should I care?
Because it's one of the few good FREE games, it promotes historical accuracy, it's fun to play, it has multiplayer and anyone can contribute to the game, for example if you're an historian you can check the accuracy of the civilizations, propose and help create new ones of the time period, if you can program you can help the team or create a mod yourself, if you have 3D modeling skills you can create new models for the game, etc... without having to ask permission to anyone. The game has a free p2p multiplayer.
>Why do you posted it in this board?
To BTFO all the "hurr durr there is no gayming or leenooks!!!!!".
Personally, I'm not affiliated to the team, but I think the development would be faster if more people play and contribute. Also, it would be nice to have more opponents in multiplayer.
