They are working on M+KB support.

Or you could just give us mouse and keyboard support, Jesus.

@chaac would be nice for easier access to items but that's the only real gain you will see.

More buttons to map is the only thing you can really gain. I know the old argument between M+K vs Controller.

The thing about Sea of Thieves is that it's an ultra slow pace game is not comparable to the FPS combat shooters like Quake and Unreal Tournament where M+K actually granted real advantage through unlimited mouse sensitivity and resolution.

Sea of Thieves on the other hand is very slow pace; it has been engineered to be played with a controller, while supporting M+K function.

If you feel as if you been more key binds, then you can easily upgrade to the X-box 1 Elite controller.
