... it was in a box. At a local video game store. Paid 20$ for it, and saw absolutely nothing suspicious.

Edit - I think I might have been taken. I just looked around the internet a little bit, and I have the distinct impression a manual is standard issue, whereas mine is a pdf on the install disc, the cd key was stuck to the cd case, and there was nothng else in the box. Absolutuley nothing suspicious indeed. I feel foolish upon reflection.
