What to look for: In the syllabus, see if the topics are specific to games, or more generalized to other media. If you want to make games, specifically, then you'll want classes that have readings and homeworks that involve games -- not movies, not literature, and not the World Wide Web. Of course, the reverse is true if you want game development to be only one option of many.
What to do: Look through the syllabi that you receive, paying close attention to the assignments (readings and projects). If there is a textbook, find it at your local library or book store and skim through it. If a syllabus is not available, ask some students who have taken the classes if they might have an old one; at the very least, ask them if the class is about video games or if that's only part of it. Also search the public website; occasionally you'll find that certain parts of a course are unrestricted access.
What to watch out for: A lot of classes (and majors!) have titles that sound like they focus on games, but then you find out that they don't. A few examples (feel free to post others in the comments):
- Nonlinear Storytelling. This might be a class about interactive stories in video games. Or, it might deal with stories in other media that are told out of order, like the movies Memento and Pulp Fiction.
- Digital Media Production. Could mean game production, in the sense of actually creating a video game. Or it could be game production in the sense of teaching you how to be a producer (dealing with scheduling and budgets). Or it could be either of those things for other media, like movie production. Or it could be special effects, like audio/video post-production for movies.
- Introduction to Interactive Multimedia. This might be an obfuscated way to say "intro to video games" or it might be a class in Web page design or Flash programming.
In short, if you know exactly what you want from your program of study, make sure you're going to get it!
