Hello,
expert in game development here. I can implement for you a GO game where the user plays against the computer.
Do you have a description of the required algorithms for the AI ? I can implement anything if I have the algorithm.
On what OS do you want to be able to run the game ? I'm thinking at using C++ and OpenGL (or SDL) for max portability.
Thanks and let me know if you are interested to work with me,
Paul
