you should have no problem getting into game programming with that list of skills. your math education is deeper than mine, and i do alright so far. i only went up to business calc and elementary statistics. why dont you email me and tell me what areas you are interested in and i can help you from there. do you want to actually code an entire game engine, or are you more interested in just using someone elses and focusing on the physics and gameplay? do you want to start out in 2d, or jump right into 3d? tell me what kind of projects you have worked on before and, if any, game related things. maybe we can work together on something too.
i think you can get my email address from my profile, i hate to put it in the text of message boards because of spam.
