I don't play video games as much anymore, usually I stick to sports games and occasionally get sucked into a huge game like Oblivion. I spent a couple nights a week or two ago completely enjoying Portal. That might have been the most fun I've had playing a video game since elementary school. I'm also looking forward to renting Assassins Creed one of these days.
As for Call of Duty, I've never been able to get into first person shooters for the most part. Also, I really don't care for playing games online. But, I do have to admit I had more fun playing Call of Duty 2 than most other FPS games.
