Activision were very unimpressed by the modding community for MW1 and by the extreme longevity we had come to expect from the CoD series.

It is not in Activision’s interests to create a game that we keep playing for years… where would be the incentive to buy the latest crappy thing they bring out?

Think about it, MW1 cost $50, of which the publisher/studio gets about half. Players are then “free” to play forever and to keep improving the game experience with new maps, rules, etc. They never get another penny.

The changes are part of an increased desire to monetize the PC market, or possibly, to push the users onto the consoles.
