If anyone here is like me and has a PC with XP or Vista, then consider getting the new Call Of Duty 4: Modern Warfare.
I pre-ordered it and got the game Tuesday, beat it on Thursday. That was playing on Regular though. The graphics are amazing and the fact that you can shoot through walls with different types of weapons is EPIC.
Another part about COD4 is the Multiplayer. As you play servers and gain exp. "points" you go through different ranks and also get to have perks and weapon enhancers.
Example: [Allies]: After you are killed you can pull out a pistol and shoot whoever is around you, this is called Lionheart.
[Terrorists]: It's the same concept only with a grenade. After you are killed, you automatically have a grenade armed near your dead body to kill unsuspecting players.
I think the game is very good and the graphics are the best I've seen on the PC. Shadows and fire are almost real. You can go on to youtube to watch the demo level and one called, "One Shot, One Kill", which is the sniping level.
Here are actual screenshots from the game.
