Booty grabing is all about cooperation and that needs to be designed for
Rare talked about their upcoming title Sea of Thieves a bit and elaborated on the intricacies of designing a game with cooperative mechanics in the foreground.
Sea of Thieves is a cooperative multiplayer game about pirate life, with a minimalist UI and lots of focus on immersion. Players can engage in ship to ship cannon blasting, treasure hunting, drinking, sailing, and generally being a maritime menace, all in good spirits. An exact release date isn't known yet, other a vague Q1 2017 announcement for Xbox One and PC.
