This game is just very good at what it does, in the genre of point and click story driven games, it doesn't get much better, the art is very good, the story is well written, the players ability to shape events by making decisions, both thought out and in the heat of the moment, makes for a really good experience and a strong feeling of involvement. It feels like your decisions matter and at times it can even put you under a lot of pressure, especially since the game does such a good job of pulling you in and making you care about the characters.
If I have one complaint it's that this game does not let you rebind keys, and since I have an azerty -not qwerty- keyboard it made the walking around really awkward for me, but despite this I really enjoyed the game. Hell even the DLC was fun
