If you are interested in game theory then you will enjoy this subject. Loads of topics discussing both theory and some applications like screening and auctions. Some is revision of stuff from 1st and 2nd year Micro, some is new. I hadn't done any economics for over a year before doing this subject and not once did this cause me problems, if that's what you are worried about. Lecturer is good but his English isn't the best which caused some confusion (for me, at least). There were some times when what was said in class was a bit vague (not enough concrete definitions) but it was ok to clarify with lecturer. Tutorial attendance is vital: while his personality is a bit jarring, my tutor Daniel (who makes a whole lot of supplementary stuff) was extremely good at showing us how to approach different types of problems. Overall a good subject, quite easy, and quite interesting, and admin side of things was also good.
