Nearly two weeks ago I picked up several new games, including Gears of War. I tried it first, and since then I've had to force myself to sample the others. It's that good.
No single aspect of this science fictional third-person shooter is novel, but each is state-of-the-art, integrated into a cohesive whole, and polished until it shines. It's a joy to play.
So far, I grade it A.
Enough scribbling, I've got aliens to frag.
