The Long Dark is already on a very, very high level - even in early access.
Why? Because of the incredible amount of realistic details, such as

+ The weight you can wear depends on the fatigue of your character
+ If you walk up the wind, you are slower and need more endurance
+ The wind force has an influence on your felt temperature
+ After a snowstorm, many new branches are available
+ If you eat salt cracker, you get thirsty

But that's not all. Further arguments:

+ A convincing I am-completely-alone-atmosphere
+ Well thought-out regions with many interesting areas
+ Food is scarce, ammunition even scarcer (collect arrows!)
+ Skill-system (you'll get better in making fire etc.)
+ Highly incentive ( "Do I survive the next day?")

The graphics have their own comic-like style. Thanks to Unity Engine, it is very low on hardware resources.
However, the setting is very impressing. If you are sitting in a hut and the winter wind blows outside, the fireplace flickers inside ... these are moments that only a few games can give you! I also like how the character expresses his emotions. He will integrate into what is happening, for example, when he groans from exhaustion.

Conclusion: A very high-quality survival simulator with very realistic requirements. Although there are only bears and wolves as opponents, the game has quite its creepy moments
