Could you not get all the books etc you need to learn about game design now and all the equipment you need, then put your all into designing games? Then you could put a portfolio of your work together...is that not the best way to get respected as a game designer, rather than going to uni and being shown how you would design games, along with having to learn about lots of stuff irrelevant to game design...?
what's your situation now? are you at school studying? i don't think you were very clear, so it's hard to advise you on what to do about gcses
