What Remains of Edith Finch
This is a short game about the last remaining member of a family who may be cursed to die in unusual ways. She returns to the family home and, whilst exploring it, uncovers the stories and ends of the various family members. This is undoubtedly a very good product, but it's more an experience than a game: gameplay largely involves moving Edith to the different locations and prompting the stories to unfold. It's unsettling without being sinister - don't expect fireworks. The closest comparison I can think of is Firewatch.
However, the stories are all told in clever and charming ways: through a flick-book, a daydream, a horror comic, even a mini-game where you play a baby who has to move a wind-up frog to trigger events. It's ingenious, beautiful and slightly macabre. Ultimately, the story falls a little bit flat, and it feels slightly like a demonstration of different ways to involve a player, but it's genuinely impressive and worth a look.
