When I started there weren't any game development degrees, so we had to pick and choose the things we thought we'd need to learn on our own to be able to do the job. Now there are a lot of places offering degrees. They are very different from each other. Are you looking to do art, programming, level design, or something else wishing the game industry. The classes you take may be very different depending on your goals. Some schools will have you take an overview of all of the disciplines, not such a bad idea, so you'll know what it's like when you're complaining about the artist not doing it the way you wanted, you'll know how hard their job is. Not to pass the buck, but this is a very good question for you to ask the schools you are considering attending. Find out what they do, and see if it makes sense to you.
