Rare had not one, but two massive announcements at X019. Not only are they releasing more Sea of Thieves content, they announced a brand new game called Everwild.
The game is still early in development but it focuses on a natural and magical world that players can explore. It seems similar to Sea of Thieves in the sense that you’ll be playing with other people online, and the world will really be what you make of it.
It seems to be super early in development, as we didn’t get a bunch of information about it, but anything from Rare is interesting nonetheless.
