Thatgamecompany is best-known for Journey, a singularly beautiful adventure-puzzler with a mysterious co-op element, whereby unknown other players will drop in and out of your own journey as they make theirs. This idea seemed to be the genesis of the studio's next game, Sky: Children of the Light, which initially launched on mobile devices, aiming to expand the idea of semi-anonymous co-op across more players in environments with greater scale.
I played it on release in 2019 and loved it, particularly how it managed to capture so much of what made Journey special in a more open-ended style, packed with mysteries. It is definitely an MMO but it's also one that works like no other, and one where the limits the game places on interaction and identity work to foster a unique atmosphere. All of which is to say that's very good news Sky has now appeared on Steam and can be wishlisted. And according to its store page, will include cross-platform multiplayer.
