Call of Duty:Modern Warfare 2

I dare to say that Call of Duty; Modern Warfare is possibly the best single campaign I have ever played in a FPS.

I agree with your assessment. I thought it was great and the multiplayer still entertains after a couple of years of gameplay. I got bored of WAW after several months and returned to MW. I tried Rainbow Six Vegas 2 recently and kept comparing it to COD4. There is no comparison. I look forward to the release of MW2 and little else this year.
