I started the game yesterday, pretty disappointed so far. I encountered some really weird save bug where I reloaded my oldest autosave by mistake and it reverted all the later saves to saves earlier than that one. Kind of hard to explain, anyone else had that?
Other than that the controls are unnecessarily weird (maybe I could change them, haven't looked into that) and I found it hard to get a sense of where I'm supposed to go. I just ended up traversing the first mission, completely missing the hostages. I have absolutely no idea where they were being held. I guess both of those things were kind of true for the original too though.
The AI is pretty cool, I'm getting caught a lot. I guess most of this is because I'm coming from 120 hours of 'sneaking' in Skyrim. And the music is fucking superb. The way it just lies there in the background, waiting to explode - awesome.
