I'd say buy it if it's 50% off.
I get what you mean @Rick_D, I pretty much feel the same for a lot of aspects… I just think they missed out big time with the pacing. Also TV show would have definitely worked better if they did something a-la Alan Wake with the webisode prologue.
That's why I'm disappointed, seems actually a step back from Alan Wake. Also I bought the collector's edition being a Remedy fan boy, and the blue ray doesn't work on my computer, Sam Lake was unable to explain some concepts without avoiding spoilers (which was unnecessary as I was perfectly able to understand what her meant without the examples).
What do you think of the combat, you played on PC, was it running smoothly? I wonder if my problems with that aspect of the game are tied to performance. I'm tempted to replay it and blaze through to see if it's just my exploration addiction that spoiled it… at the same time I want to play other stuff.
Might be that going back to it in a year time I would love it, like I did for Alan Wake.
