When you click the can you run it thing...make sure you have the recomended hardware.
If your computer is like mine and only has 512mb of ram and a 128 mb video card then i would not recomend getting this game. I had to put everything on low settings and it still lagged. Either upgrade your pc or get a 360.
But if you have a good computer this game is pretty excellent. By far it surpasses the previous ghost recon games. The details look great, the controls are pretty simple, and the gameplay is fun and intense.
This game has many ways for you to control your squad which makes taking out the enimies easier and less frustrating.
If you are a fan of the other ghost recon games, a fan of squad based shooters, or just a fan of any shooter then GRAW is the perfect game for you.
