Art institutes and others, eh
As far as Art institutes (ones owned by the Career Education Corporation) i might stay away. There are cheaper, more realistic approaches to the game art industry. I'm currently in the middle of leaving one CEC college, to attend a state college. Their art program is better, and there aren't any current lawsuits against it.
As stated above by HagNasty, i have heard good things about Seneca, but alas, have never been. Try to look for something that fits you, and you're budget. Many state colleges actually have good programs, and better equipment than some pure art schools, and they won't get you $40k into debt. For example, the guildhall at MSU, i have heard good things about it as well.
I hope this helps.
