Modern Warfare 2, while no doubt being a good game, is not nearly as good as Modern Warfare. The campaign was good and very fun with some jaw dropping moments, such as the invasion of Washington DC. The graphics aren't bad for the games age, but it certainly looks better on PC when compared to the X-Bone. The amazing events of Washington DC looking hellish and very real with recognizable monuments such as the Washington Monument and the White House being partly destroyed. The single player is pretty short, took me roughly 4 hours to complete.
To me this is the last of the COD games that I actually enjoy in the series. After this they are all the same, same graphics, same story, game play, everything. While this game is not on the same level as say, Half Life 2, it is still a pretty decent game.
