The idea behind Ether Pirates is a multiplayer game where the player can gather items and characters on a blockchain based system. These objects can be traded from user to user and have real Money values. 

Also it is possible to get other developers into the Blockchain to create a multiverse of games where the users can use the Items within other games.

Due to the money pool I got the game is just running on a testing Blockchain (the Kovan Chain) where the items don't have a real money value. But are simulated like they have a real value.
