Well the atmosphere and story are great, plus there are a number of different ways to enhance yourself and quite often you have to choose between many different options and, so far, all those options have their uses...

Looks quite nice too...

Other than that though it is still your typical FPS, doesn't really do anything new.

Have you tried the demo yet?

Must hurry and finish Bioshock though as I really want to play the NWN2 expansion!!
