Hmm... Now, I play MW2, its a game that took a while to grow on me but, eventually, it did (I would like to note though that I play it socially with friends).
I like the game now, but not enough to pay any ammount of money per month for it. The fact that its campaign was insultingly short for $60 means the multiplayer is the only justification for purchase (granted, mine was a gift, but still).
Now, lets think. Modern Warfare 2 is fun, mostly because of the people I played with. I find other games to be far more entertaining. Halo 3 was much more fun for me, in all aspects. Modern Warfare was a lot more fun. The new MoH looks a lot more fun. Team Fortress 2... Nuff said.
I dont need MW2. Nor does anyone else. The demographic for CoD is High School and College aged Males. THEY ARE NOT KNOWN TO HAVE MUCH DISPOSIBLE INCOME.
Do they hire people who do demographics? This is a bad idea.
