I started playing it after work yesterday after work for about 4 hours. Definitely all around good, the only things you'll need to find it in yourself to forgive is:
- the loading times can be a bit on the long side, even for loading a quick save, but only compared to other recent games, however its nothing you can't get over (20-30 seconds tops)
- the conversations have great dialog, and all voice acted well, however the animations of characters during these sequences are not as smooth as they could be (like in Mass Effect)
Otherwise its a pretty good experience, worthy of being called a Deus Ex game. Here's a few of the things I really liked:
- the combat isn't about sponging damage or emptying a whole clip in a single foe, if you take more than a few hits you will die (at least until you upgrade your armor augments), and same goes to most enemies (except bosses I hear)
- the stealth play is rewarding, and the hacking mini-game isn't too bad
- the story is pretty engaging
I did have one interesting situational bug where I gained access to the police station, being able to walk around the place without the cops shooting at me. However, as soon as I stepped out the front door of the police station after finishing the quest inside the cops shoot and kill me and I have no chance at all to get away as I'm dead in like 2 seconds out the door. So I ended up having to find the roof access and exit that way just to avoid being killed. Not entirely sure who I killed or what I did to make those cops outside hostile to me but oh well at least I got past it.
