The only course i personally know about, is the Computer Science course at Brighton, for which there is a specialist games course, as well as a more general one. The first year modules are standard between the two, to give you the same computer science grounding, so it will give you good thought for what degree you want to specialise.
I didn't take the course, but knew people who did, who got quite a lot out of it, but that the courses are so specialised does mean you are more restricted at the end of it as to what you can do. What i will say about Brighton though, they offer really good 4 year sandwich courses, with a years placement in industry, and have good links to companies which you might be able to use as a starting point for future employment. If this area is something you are certain you want to go in to, i would say its worth looking at.
