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.
When you do get into a building, however, you’re rewarded with a detailed environment to explore. Houses are gratifyingly individual, with hints of the personalities of their departed owners. Pubs feel familiar despite the prices on the chalkboards – £2 for curry and a pint, 50p for an ale – which perhaps reflect the time period more than the cars and phones and Rubik’s Cubes.
