I just bought the US GOTY edition, and I get a wrong CD-Key message.
I thoroughly checked the letters I inputted to see if that was the problem, but it's not. I guess I will send a message along with a scan of the manual and the error message to customer support and see what the problem is. Heck, maybe I will even try my original OFP key. Anyway, I can't understand how the heck they printed a wrong CD-Key in the manual, unless they accidently threw a original OFP manual in the GOTY box. It does have a very uncanny resemblance to my old OFP manual, except for the fact that it's not all beat up like the old one.
