However, it's not just all the different modes of play, but rather the sheer attention to detail that separates Perfect Dark Zero from other first-person shooters out there. It's a gorgeous-looking game, especially if you play it on a high-definition display, and the beauty's more than skin deep.
....
From a gameplay standpoint, Perfect Dark Zero is highly refined. It doesn't stray too far from convention, but it features some interesting twists in weapon and enemy design, making for a much more entertaining experience than the average shooter.
....
Perfect Dark Zero's cooperative play mode is easily one of the best things about the game. You can play through the entire campaign cooperatively online or in a split screen, and the tactical shooting is even more fun when you're coordinating with a friend. However, what's really great about the co-op mode is that it does more than just throw a carbon copy of Joanna Dark into each level with you. Instead, player two will control some other character, who may begin the mission in a different place and be forced to overcome different obstacles from player one.
....
Taken as a whole, Perfect Dark Zero is decidedly one of the best, fully featured Xbox 360 games so far, and it's a compelling reason to spring for the system if you've been on the fence. While the game doesn't reinvent the first-person shooter, which has been a mainstay of action gaming for more than a decade, it delivers one of the most highly refined and spectacular examples of this brand of gameplay to date. From its ravishing good looks and totally first-rate audio, to the believable feel of its outstanding weapons, to its wealth of single- and multiplayer options, Perfect Dark Zero delivers just about everything you could hope for from a first-person shooter.

the bad and the ugly is quake 4
from [linkd=gamespot review of Quake 4]http://www.gamespot.com/xbox360/action/quake4/review.html?sid=6140243[/linkd]

When running on a modern PC, Quake 4 looks fantastic, using the Doom 3 engine to display the alien world of Stroggos in a sharp, defined level of detail. A quick look up at the sky or at most of the game's wall and ground textures shows that the Xbox 360 version has significantly muddier textures. In addition, the frame rate is sort of a mess. Any time the action gets heated in a large or complex-looking area, the game starts to spin down to a surprisingly low frame rate, regardless of whether you're playing in HD resolution or on a regular TV. At some points, it gets so bad that the whole game starts to slow down, as well. You'll know when that's happening because the rate of fire on your weapons slows way, way down. Even when there's no action onscreen, just viewing the environments is enough to make the game run at a noticeably choppy rate. While there are still some cool-looking areas, the frame rate troubles drag down the entire experience.

Quake 4 could have been a great game, but the performance issues are so heavy that they have a negative impact across the board. The gameplay suffers both online and off because you often can't see exactly what's going on. With the Xbox 360 launch already stacked with quality first-person shooting, Quake 4 sits squarely at the bottom of the pile.

am surprised microsoft let them release it in obviously such a poor state.
