and answer is unsimple, at best. We did a lot of the research that you're looking for answers to before he decided it wasn't what he wanted to do.
Any school can lead to a career in the field of video games if you learn/know the right skills and have the talent. However, this is one field where school choice can make it easier to get into the field (It's a notoriously difficult field to get into. Something like 500 qualified applicants for every opening.)...referencing a thread from last night, an alma mater can set you up with a alumni network and connections in the field. There are a number of schools which exist explicitly for this field and to teach the precise skills and knowledge needed to work in gaming and already have strong alumni networks in the field to garner internships. I have a very high opinion of University of Advancing Technologies.
http://www.uat.edu/ So why I'd advise toward UAT...it's pretty much the only school specialized in the field that is anything other than a industry-specific trade school and one of a very few to go on to offer advanced degrees (MA, MFA, and Ph.D). None of the other programs my brother looked at really jumped out at me as a great school. To be frank, Lil' Chan wasn't exactly MIT material...or even UConn material though.
I'd like to know more about your boyfriend. Who is he? Does he frustrate or get bored or discouraged easily? Is he a codemonkey? (Someone who likes to look "behind the scenes" of his software and figure out how things work)
How is his imagination? (Seriously...the thing that sets the successful apart from the talented or good is imagination and drive. You've got to have both in spades.) Is he artistic? What part of the game making process does he see himself in? (This is the $1M question...there are as many sub-fields of game making as there are fleas on a coyote.) does he make mods of games or design new skins for characters? Does he write stories or make home cinema?
