The best thing about GRAW2 is that it's a combination of Splinter Cell and Rainbow Six. It takes the cool gadgets from Splinter Cell and brings it to the battle front. That brings a feeling of modern war fare instead of the overused cliches of Word War II games such as Call of Duty and Medal of Honor. What the gamers really need is the evolution of war in a realistic sense. All the technology available in the game really do exist such as the hover spy cams, the cross cams, and the camera-gun which enables you to shoot while in cover. The game-play scheme is both addictive and fun. However, what the single player story lacks is the length that we wish the game would've had.
When you finish the single player modes in Gears of War, GRAW2, Lost Planet, and so on you feel quite disappointed that you've finished such a great game and playing the campaigns again wouldn't be as much fun.
However, one thing that really busts your balls in GRAW 2 is that enemies with normal machine guns can spot you from a very large distance that only a marksman would be able to view. However, overall the game is great.
When I read the review, I was astonished to find that the person writing the official GR review didn't like all the HUD displays available in single player modes. The Hud display is great and very functional. However, I agree that it's a little bit overused in the game. For example, it would've been better if the displays were triggered by some button.
Good Game overall, really worth your money, and a good continuation of Tom Clancy's successful game series.
