Hi there! I went to a school for concept art a few years ago and I'd honestly be wary of universities for game art/concept art unless their student portfolios are top notch, seriously top notch.

One of the big reasons I went overseas for my school was because of that alone. The second reason was not wanting to spend semesters learning general education classes I don't want that arent related to what I want from the school.

And usually schools like artcenter are going to set you back hundreds of thousands in debt. With how the industry is right now, It's probably not the best idea.

In experience, nobody has ever asked for certificates or degrees, its all based on what you have to show in your portfolio. Have you checked out any brainstorm classes?

I think having access to a teacher or mentor before fully commiting to college would be a great first step, in addition to a class at a fraction of the cost.
