I'm not going to lie I can only play the campaign because I refuse to pay for online so my review may be a bit biased. I thought the game was lacking something in that I didn't really feel like I was playing the final gears game but more like a copy that went kinda bad. I thought the campaign was short and sometimes I didn't really understand why i was doing what I was doing and no, its not just because im a bad player I just thought that the story didn't really express any emotion and made me more separated from the experience. The action wasn't as awesome as some of the other games in my opinion and the end of the story was nothing special. All in all, I thought that the third gears game just wasn't as epic as it could have been and yet, I know everyone is going to disagree for some weird reason and because i sound stupid for not playing online but for those in my predicament, you may find my view more helpful.
GOW3 is like the return of an old friend. The graphics seemed better and the action was a little smoother. There was a feeling in this one that you could feel the comraderie of the figures. Great game that I will eventually buy and add to the first two. A keeper.
