The only colleges I know of that that offer specific game design classes are in Cali. I don\'t know the exact school but they are some of the bigger ones. I think either UCLA, UC SAnta Barbara, or USC is in the process of testing out a game design major. Other than that you can major in Computer Science at pretty much any 4 year college/university and intern/hump your way into the gaming industry.
If you are absolutely POSITIVE that you want to do game desing you should check out Digipen in Seattle.I believe they are partially owned or funded by Nintendo and they focus on nothing but game desing.
