Dang, had I known both Dishonored and Borderlands 2 would be going for 15 quid each I'd have bought them from Steam. Still, £18 & £17.50 respectively ain't so bad I suppose.
Am also tempted by F1 2012 but I think I've spent quite enough for now. Still got F1 2010 which I paid a fiver for on PC with lots of gameplay left in it plus F1 2011 on Xbox which I got for a tenner which I haven't played at all yet, so this time around I'll probably pass.
The Serious Sam 3 extra Jewel Of The Nile was well worth under two quid, enjoyed that, just three extra levels but hey...
