Personally, I really enjoyed the game. It's probably one of the better new IP games I've played in the past few years. I found the story to be pretty easy to predict, yet I still was really drawn into it, which I can't really say about a number of others (Skyrim, for example). I believe, in part, it has to do with the length. I've found that lately a lot of the new games with lots of content and that last for 30+ hours seem to have a story that's dragged out and hard to get drawn into. For me, a game that is short, sweet, and to the point is far more enjoyable and has a higher replay value than games that take me weeks to get through to the end. The fact I feel this way may have a lot to do with the amount of time I have to play, as well. I'm far more likely to be able to focus on a story that lasts for 10-15 hours than one that lasts for 30+ and is drawn out across several weeks. This is obviously a personal observation.

The Low Chaos ending felt really complete to me as well, I think they tied it off really well and didn't leave me feeling like a sequel was necessary to finish the story. The High Chaos ending was kindof 'meh' to me, but again, that's probably personal. It also seems that some of the atmospheric storylines change, either randomly or based on your decisions. I haven't figured out which, but I noticed some of the dialogue between characters changed pretty dramatically between my first and second playthrough.

The gameplay is fun, that's been hammered out by other folks. I wish they had some sort of progress check you could do on the missions to check for deaths or alerts, I found out the hard way that dropping corpses kills them and had to replay a mission as a result. That was frustrating and it's easy to accidentally kill KO'd guards. I'd also like to see more NPC interaction outside of the pub, but I can see running around trying to kill someone in a plague infested city being a reasonable excuse for that not being there.

For the purpose of the game, I think the length is perfect. If it had been too much longer, I think it would have gotten repetetive (see Assassin's Creed), if it were too much shorter, it'd be too short. The fact that most of the interesting content is in side quests, allows you to blow through at your own pace during several replays. If you want to blast through a mission just killing everyone, it'll take less time than if you go explore and find all the non-lethal ways of finishing the game. Had the game been too much longer, the replay value would start to diminish IMO.

I want to try and play through without using any powers, to see how far you can get. It seems like a lot of the areas that require power use (outside of The Void), require it to access runes. If you aren't using runes, it almost seems like you could sneak through most of the game without using any powers at all. We'll see how that pans out ;)

I should also note that the INI files are very revealing and have a lot of interesting content in them, some of which looks like some form of network play. I was really amazed at how verbose and robust they appear, when I finish this playthrough, I want to fool with them some. I haven't seen a game with so many configuration files and fields before, it appears a large amount of the game is configurable, even down to AI components. There appear to be some really interesting developer/debugging type options as well.

There is also an empty "Editor" subdirectory in "bin/Win64", but I'd venture that the editor and the game are a part of a single build package and that just happened to be left over (based on the editor being a 64-bit build and the game 32)
