I played an hour into IW and can further confirm that it's pretty bad. Technically, the game is sloppy. You can't enable AA and bloom at the same time, which isn't a huge deal but the game looks bad anyways, especially for an Unreal 2 engine game. Tons of loading screens, and for whatever reason, the game minimized ever time you hit a loading screen and then goes back to full screen. Really annoying.
Gameplay wise, it doesn't seem much better. There are points where it seems cool, but the inventory is too small, the targeting reticule blows hard, and none of the choices you're given are anything you want to do. Uninstalled.
