The openwar platform/engine for the iOS game Samurai Wars (https://itunes.apple.com/app/id442916628) that I've been working on is now on GitHub (https://github.com/openwar/openwar).

Currently Mac-only (will port to Windows in the near future) and is built using C++, glm and some custom OpenGL code.

Samurai Wars is a real-time tactical war-game for two players set in the Sengoku jidai period of medieval Japan. Be a samurai warlord and command your troops on the battlefield, using tactical skill to defeat the enemy army. It features realistic battle simulation of thousands of individual soldiers

Next up I will complete the map editor. And after that, it's lua-scripting of battles.
