I got a chance to play this today, and while I was playing with an attitude of 'holy jesus this is gunna be good', it just wasnt really...
Did not impress me.
Sure, its good. But it lacks spark. The ragdoll is pretty terrible. Some parts of the environments dont look that good, unrealistic for some unknown reason. A chair reflects too much light? Theres something wrong with the way that road looks, kinda thing.
The guns..well thers one gun that has a single shot scope mode, automatic mode, and a grenade launcher.
What? Why use any other gun? Why would they put this in the game?
There really isnt anything impressive about the game at all in my opinion, though only from a limited play. It seems that it will sell on the basis of the name Perfect Dark, and the fact that it is a shooter on Xbox 360.

Is there something I'm missing? Anything that makes it really good? It was cutting edge back in the day! But now its just a shooting game that leaves me unimpressed.

Thank you. I like to hear that I'm right.
The '64 game set so many benchmarks. The trilogy lives up to them...but doesnt create anymore. It just has all the old stuff, stuff thats now being used in every other game...

That's easy enough to explain: The ragdoll sucks. It's in so many games now, some have good ragdoll, some don't. This is in the latter catagory.
