That's a good degree to be doing I'm studying Computer Science, University of South Wales, but living with three people doing their masters in computer games development I think they focus on C++ and C# mainly.
You should look into if your uni does an MComp course. Essentially you do the first three years as normal but don't graduate straight away, you then do a fourth year for your Masters but it counts as undergraduate study. You can get student finance to pay for it as its undergraduate rather than graduate study and you end up with an MComp rather than a BSc.
Iv'e seen quite allot of the content of your course as some of the modules are shared with mine, Maths/Operating Systems/Networking/Graphics etc. Really good course.
