Simply an outstanding and intriguing story with a rich and dense atmosphere. The world really feels lived in, and the artstyle and attention to detail really shows how much the developers cared; as well as accopmanying the plot greatly.
Graphics are just what you need it to, the characters are super fleshed out and modelled to perfection.
The gameplay may seem a bit unintuitive and straight forward at first, however, this is simply not the case. The gameplay flows extremely well and after you get the hang of it, is really fun.
Overall I had to get a 100% completion of this game, including all Steam achievements; its simply that good.
Amazing experience, go buy.
