Just picked this up last week and haven't been able to put it down since. Regardless of its flaws, it's the best immersive sim I've played in quite some time. You can tell the game was made by people who wanted to do something cool and different, instead of just a derivative Skyrim clone.
Also, I have to say that one of my favorite things is the armor system. I love the fact that there are so many layers and gear slots to choose from. Just last night I was able to finish assembling a full suit of plate, which is a really satisfying accomplishment.
The only thing that throws it off a little bit for me is, how you can just equip and unequip your armor at will. That's fine for clothing, but when it comes to chainmail and plate, you really can't put it all on without help from another person. So it would be cool if putting on / taking off armor was limited somehow.
Now I know realism takes a backseat to fun, but I think this could be good for gameplay too. The game has systems for Conspicuousness and Noise -- presumably to create a trade-off between heavy armor and stealth -- but if you can just instantly take the armor off every time you need to do something sneaky then it defeats the purpose. If you were limited to say, only being able to change armor at home, then it creates a strategic decision -- the player has to choose whether to tailor their equipment for a combat or stealth approach, and then live with the results.
