Crown and Cutlass is a 3d pirate action/adventure game in the spirit of the old Pirates! game. It is simultaneously being developed in Linux and Windows, with a strong emphasis on cross-platform compatibility. The project is still early on in development, although it is just beginning to look like an actual game.
