Clocked 10+ hours so far (VPN), its pretty good. Graphically its NOT a good looking game, especially character models, faces and dialog animation, often times it creeps over into the realm of UGLY. Bolt on DX11 for a few special effects that certainly doesn't fix low poly models and bad texturing. Gameplay wise and your choices for approaching situations is only matched by the original Deus Ex, clearly a tremendous amount of effort was poured into this part of the game. I also stand by the critics on this about bosses, at least the one boss fight I had so far was disproportionately bad compared to the rest of the game mostly because you are limited with one way to approach the situation.
Overall, if you can overlook some of its serious technical limitations, there's a great game. I know I sound negative, but I'm quite pleased with the game as a complete package, much MUCH more worthy attempt at a sequel than Invisible War. Worth mentioning that the UI is quite good, which is very rare among modern games. Grid based inventory!!!!
