Woo, thanks for the heads up! I set Steam to load up directly into my library and I haven't been great about checking for occasional deals. I would have missed this entirely! I had about $10 in my wallet from selling cards so this became an instant purchase.
I never finished 2033 because my motherboard got fried while I was playing that and by the time I got the PC back up and running I felt I needed to start all over but had too many other games to play and it got left behind. Now my only question is do I go back and start 2033 over before playing Last Light or just jump straight into LL?
