The atmosphere in a game can be just as memorable as the story or be a character itself. Fallout 3 proved this as the Capital Wasteland was a character all on its own. A great atmosphere is something that can draw you in and make you feel a part of the world.

Observer

Just like Soma, Observer delivered an unrelenting atmosphere that is chilling to the bone, disturbing, and outright immersive. Not a single game this year touched Observer in terms of atmosphere. It was a let down storywise towards the end, but the entire play area of Observer tells its own interesting story.
