Gamespot's review is a shameless lie. I doubt they even played the game.

The gaming industry is at a crossroads. Billions of dollars on the line but few objective honest industry watchdogs. This site makes it's money in advertising from the games they review. Conflict of interest, maybe?

For a more honest review see:

"This does not channel the greatest military empire in history so much as the pale shadow of its ending; a bloated, technically corrupt and unfocused mess."

or The Angry Joe Show

As for Gamespot, if you do not diversify your advertising income and create some kind of industry credibility you will not be here in 10 years. Rich Stanton's Guardian review is an example of the future; where larger publications review games without any pressure from the game publishers. It's a matter of time.
