Its a shame, because COD4 was just epic...it was something completely new....kind of like when they came out with the first call of duty and then it slowly went down hill with all the following ones....the same thing is happening after COD4.
Honestly they'd still be making bank with COD4 instead of throwing a new version at us every and god the custom kill streaks wrecked it all....UAV, Airstrike, Helicopter was the best.
