This ranks in at least the top 3, if not number 1, in greatest single player campaign ever.

After just beating the single player campaign, I honestly must say I am having trouble thinking what to do next. I have just been so blown away by what I'm going to call the best campaign I have ever played through. People keep saying that this games only flaw is it is too short. But I think the length of the game is just about right, it tells the story great, and its just really like an amazing 2 hour action movie, except you are controlling it. It's campaign has so many well timed suprises that you are only distracted from the story line for a slight second to take care of the rows of terroist coming your way. Also after playing the multiplayer for a while. It is the best multiplayer out of the 3 Call of Duty's. I have a computer so I do not count the third. It is extremely well balanced and I noticed Activision has made considerable jumps to make the multiplayer more realistic by making it harder to snap in to prone posistion everytime you see somebody and making bunny hopping with an automatic gun or shooting to much with out your scope just difficult in general. Overall one of the best games I have ever played. I currently own Enemy territory: quake wars, World in Conflict, Madden 2008, and Supreme commander, and was playing them quite a lot. But I have honestly not touched those games since i bought this game 4 days ago.
