I should say, though, that I know a number of graduates with upper second class degrees, or better, who have a lot of difficulty getting positions (I speak for skynce). Some of them even have Masters degrees, actually, so you're not alone at all in your position.
There are fewer jobs now than there were 6 years ago, but many more graduates. Either one gets a highly sought skill, gets a lot of experience during their degree, or goes into further study, in general. I don't know how in-demand games degrees are, but I imagine that to get an in, you need a very big portfolio, considering it's viable to get work experience in it from the age of 10.
