So a more advanced engine, better graphics, destructible environments, squad based gameplay, vehicles and about the most realistic warfare game ever don't trip your trigger?
You're crazy son!!! I wouldn't waste $60 on Modern Warfare 2 Modern Warfare 3. It's basically just new weapons, reorganized perks and new models slapped onto the same half a decade old engine. I guess you have to give IW made props for being able to sell that garbage, though.
Now that I've said that, though, I'm glad nobody knows I still generally pay full price for the new NCAA game every year. At least this last year it only cost me $35!
Enhance, there are some folks that just can't handle what BF3 provides, bottom line. MW's success lies in its banality, simplicity, and the ease of which script kiddies can hack the games. It's part of the reason why Infinity Ward and Activision came to loggerheads--the former wanted to expand the franchise greatly, and the later was content to shovel the same **** out the door for $59.99 U.S. and rely on P.T. Barnum's Law of Consumer Creation and Categorization.
Considering the braintrust behind MW (Infinity Ward) has mostly migrated over to EA and DICE, it's only a matter of time before Call of Duty goes the way of Guitar Hero and Tony Hawk Skateboard games.
