Well, I picked it up.
Not really impressed by the graphics changes.
Mildly annoyed that you DON'T get the cash bonus that was there from one of the minor DLC's that I'd paid for previously, but not a big deal, it just means more trecking to the arms dealers in the first chapter.
Some improvements in the AI.
Haven't got to the boss fights yet.
Annoying body twitches during dialogue are still there, but the facial animation is definitely improved.
I'm curious to see what happens at the end of the Missing Link segment. I saw somewhere that you get to keep everything you acquire, and get back any lost augs. Given the number of praxis kits available during Missing Link, I'm wondering if that means you're going to be massively over-endowed if you just hoard them instead of using them.
I'm also curious to see if this means you can do Factory Zero in the full game now. The walkthroughs seem to imply you need augs for the boss fights if you go bare-handed. I haven't checked the Achievement list.
