How practical would it be to use Cython as the primary programming language for a game?
I am a experienced Python programmer and I absolutely love it, but I'm admittedly a novice when it comes to game programming specifically. I know that typically Python is considered too slow to do any serious game programming, which is why Cython is interesting to me. With Cython I can use a Python-like language with the speed of C.
I understand that I'll probably need to learn a bit of C/C++ anyway, but it seems like Cython would speed up development time quite a bit in comparison.
So, is it practical? And would I still be able to use C/C++ libraries like OpenGL, OpenAL, and Bullet Physics?

Cython doesn't forbid the use of threads, you just needs to use the no_gil special statements.
Beside the bindins of c++ is now functional in cython. 
We do use it for something which is close to gamedev. So while I cannot be final on this, cython is a valid candidate.
