Windward is a sandbox style action game on the high-seas! It is inspired by Sid Meiers pirates to a greater extent.
I sat down with the designer.
He and I had the exact same feelings about Pirates!, and as he described his game more and more, my eyes began to light up. Playing the game was delightful. It is available already through Steam early access, the designer invites the community to play with him on his own servers and I recommend it, the multiplayer is a blast.
