The Doom 3 gameplay has exceeded my expectations. Yes, it's a lot of creeping around dark hallways and shooting things that jump out at you. Which doesn't sound very fun when you describe it that way. But it is. I find the gameplay to be intense, engrossing, entertaining, and very much worth the price of admission. Your mileage may vary.

I even like having to switch back and forth between the flashlight and the gun. It enhances the feeling of being surrounded by dark creepy things and not knowing what's going to jump out from around the next corner.
