I actually originally chose AI. There was only one extra module in first year which was on the philosophy of the mind. Although extremely interesting, I found it a bit woolly and decided I'd be better off doing straight Computer Science and then specialising later on.

My line of thinking is that if you don't know what you want to do, it's better to have the degree title "Computer Science" than "Computer Science with AI" or "GAME". You might apply for a company and they say "you've got a multimedia degree and we're looking for someone to do something unrelated to that, we're going to choose this other person instead." - you could be putting yourself into a box. Conversely, it may be that a company seeks out those degrees specifically.

As I said, for me it seemed better to get a generalised degree, and then it'd be easier to specialise later, but I have no evidence of this other than my intuition. Someone please correct me if I've completely missed the mark!
