I finished this game yesterday, described as a 'walking simulator'. There are no people (in a physical form) or animals to interact with, just the landscape and houses of the villages. 

 I loved it, it was so well designed, the landscape was beautiful and at times I felt like I was walking through an episode of the Archers (but with an apocalyptic twist) 

It also had an wonderful soundtrack which I felt was very important due to the amount of time you spend just 'walking around'. 

If you are at all into 'indie' games and have a ps4 I highly recommend it, you will be blown away.
