COD is free after you pay for it, plus you buy the expansions, but there is not even close to the same amount of overhead that goes into a game like that as there is that goes into a MMO. It takes a lot more work to make and maintain a MMO than it does a FPS game. I'm not sure of the exact numbers, but I know that it takes a ton more money to do a MMO. They are by far the most expensive video games to make.
