I attended UACT(what they called it before they dropped computing) for a couple trimesters, and the school's alright. Having seen both UAT and Digipen though, if you are really serious about getting into gaming I would recommend Digipen over it.
UAT is a fancier place for sure, but if you think it you're going to have more of a "college life" going there, you're mistaken. There's really not any more ladies at UAT than DigiPen, and it's not like you're going to have the time anyways so why kid yourself. As for the tuition, they're pretty close to the same, but at UAT you can get Federal Loans where I'm not sure if they're available at DigiPen(+1 for UAT I guess).
The real reason I recommend DigiPen though is this: The place you go to class is the same building Nintendo's NST is. You're right there at Nintendo were you can plant your feelers and get connections. UAT can't offer that, though at times they'll get a guest speaker, it's nothing compared to making friends that are already in the business. If you are serious about breaking into the game development scene, get into DigiPen!
