Query: Best PC game ever.

This is by far the best PC game ever created. It is also one of the best First Person Shooters ever made. This game has absolutely gorgeous graphics that will draw you in to the game. It is so much fun that sometimes you will forget that you aren't actually in the game. And if you like horror games, the level "We don't go to Ravenholm" is scarier than anything in Doom 3. This game is very fun and is definetley worth the $55 it costs. The only problem is your computer must have a VERY good graphics card and must be a fast computer. Overall this is and Halo 2 are the most fun I've had in games for a while.
