Do I need to play Sea of Thieves with other people?

Sea of thieves is a social game. Be a bit careful about how wide you cast your net when playing with a group, especially with those you don't know. It's probably more fun to play with 2 or 3 others.

It is a game designed to be played socially, even though getting your treasure safely back to base may seem something that a brave pirate might undertake all by himself. Here, you need others or you won't get the full enjoyment of the game. Link up with a few friends.
