Im gonna have to disagree with the gamestop review
Now to the goods. Graphics are amazing, although I will say as a personal taste, I thought it was a downgrade from GOW1. Artistically speaking, the melancholic and metallic environment painted with utterly pale hues really reflected the story they were trying to tell, here, there is no connection, they just use realistic colors, which is a flaw for me.
The campaign is really good, and near flawless. I disagree again with gamespot here, SPOILER the Intestinal Fortitude level where you are in the worm and other levels like where you fight Skorge on the Reavers as well as the bosses add great interactive and different experiences. I also enjoyed the new variety of enemies with the large boomers, maulers, and reavers, as well as the Tickers. These experiences gave gamespot a bad taste in the mouth because apparently they don't enjoy variety or a scene where they are just shooting the same grunts over and over again... Anyways, a lot of people are similarly upset with the story of GOW2 as they are with Halo2, but I will say, where Halo2's story didn't have any kind of point, GOW2 does big time and is setting up for an epic GOW3. I think that when people have completed the trilogy they will come back and realize how good GOW2 and its story were. Not to mention, this is a ploy from epic to get people to play their game. Otherwise, campaign play is much similar to GOW1 minus those terribly annoying bats but its the variety that makes it better, graphics and engine aside.
All in all, Campaign is 10/10 and Mutliplayer is 6/10, saved only by Horde.
