Wow, this game is amazing. My brother got it for his birthday, but with him off at college now, I'm hoping to get it for Christmas. Pushing the Unreal Engine 3 to the limit, the game is seamless and looks amazing. Unlike other shooters, Gears of War is all about teamwork in a big way. All game modes, levels and scenarios are designed specifically to encourage co-operative play, whether it be with A.I. partners or human players (with A.I. teammates designed with specific strengths, weaknesses and personalities.) It's sweet.
