Are we talking OGRE games?
OGRE is fairly easy.
You just need to learn either:
Visual C++ and Code::Blocks on Windows
Or gcc 3+ on Linux / Mac OSX (using XCode)
But once you make the source code and such of said game, I could help you with any texturing/particles/materials/meshes/etc xDD
I don't do actual heavy coding.
Like, I barely know basic HTML xD
