I feel bad about giving it a 4, but I try to score based on the overall experience playing the game, and it was let down by the combat/missions at the end. (I do like the ending itself though.) That said, it has moments of absolute brilliance, especially the beginning. The dense initial hub, with the interactivity of the world, flexibility of approaches, and maybe most of all just the writing/world building was refreshing and unlike anything I've played.
