Hope this "new graphics engine" will be really new =)
I played Hitman 2 after NOLF2 and was rather dissapointed with the the graphics. There was a serious lack of detail and variety to the textures, a few areas barely surpassed Wolf3D in quality. From a presentation standpoint however, the sounds and the overall mood of the game was enough to make me want to finish it.
Then there's the gameplay which is both challenging and rewarding. Deux Ex 2 seems to have difficulty getting the former part right, even on Realistic.
