Why is CALL OF DUTY 3 not released for PC?

that's a good question. Treyarch believed that cod3 on consoles rather than pc are better performing and are actually built to play games. It is a good thing that cod3 didn't come to pc as it sucked bad with your 54iq friends and a dumber enemy ai they also shoot you until they kill you or u kill them it was that bad. I hope this answers your question.
