See the Gamekit forums http://gamekit.org/forum

The goal of gamekit is to create a basic game engine that allows fast prototyping build around open source software free for commercial use.

• Using Ogre or Irrlicht for graphics, Bullet for physics, OpenAL for sound
• OgreKit is most actively developed and in svn/trunk, the suspended Irrlicht version is in svn/branches/IrrKit.
• Engine is written in C++ and the game logic can be done in C++, Lua scripting or logic bricks
• Reads all data from Blender .blend files, with future FBX import planned
• Free from viral licenses: only using components using MIT/BSD/Zlib style licenses
• CMake cross-platform build system support that works out-of-the-box, see http://cmake.org
• Gamekit supports Windows and Mac OSX, Linux, Android and iPhone.
