Is it though?That could very well be the case yet it's hard to ignore that the main content in CoD games is the multiplayer and it can't be ignored when we look at the price.
Then how come every COD game focuses on the single player campaign when a new one is first released. Every news article and first time reveal revolves around the campaign. The mp is never really talked about until the end. (some would argue it's the same thing everytime)
Just like the ratio of Xbox 360 owners to Xbox live gold owners..same could be applied to the COD MP.
