Complex 3D games arent written in python because of pythons nature. Python isnt a compiled language, (it uses an interpreter), which makes it very VERY slow. It also doesnt have very mant GUI libraries. Python is better for computational work and AI/machine learning (though C may beat it in speed for purely computation mathmatical/cpu intensive work.)
