What should I do about college?

Yeah you probably should get a degree in Computer Science if you want to write other kinds of software and not just design games. You can take all of your generals and lower division CS courses at a comm. college, they are usually very cheap. The only downside is your GPA from there will not transfer to the university, but if you are a good student you can get a good GPA in your upper division classes at the state university and will have saved a boatload of money.
