Ever thought about looking for work with a games studio? That's about what current tech allows for in racing sims!
It's not as easy to get into as you may think most people come out of college with pieces of paper which gets them in the front door, but I'm self taught and like most things in life if you haven't got a certificate your no good at what you do!! Besides I'm a bit long in the tooth now because I'm not in my 20's
