I feel like I want to change my field of study

If you're looking to get into game design, perhaps you should try to get into an actual game design program instead of a computer science one. They do exist.

Art schools cost a shitload though, be prepared to write essays begging strangers for money.

They have a game design major/minor and some classes are purely for the art aspect...and I'm really not too keen on moving/transferring to another school. :x

I know Academy of Art is pretty not that expensive and/or classy though. My sister, who's already in college, gets letters from them every week or so asking her to transfer/enroll/have sex at their school.

You might want to consider bioinformatics, if computer science came easily to you and you are interested in working with biological subjects. If your college has that major, then you can try to convert those CS courses to fulfill the curriculum. In my school, Intro to Comp Sci (Java) and Data Structures which were CS 101 and 102 courses were required CS courses for the major.

CS and working with computers in general comes easy to me, cause I've been screwing around with them for as long as I remember. What kind of subjects does bioinformatics deal with? I'll take a look at it when I can.
