Here's a couple of pics from the event:
Flying Lab Software is currently developing a new massively multiplayer online RPG that takes place in the Caribbean of the 18th century. The game is called Pirates of the Burning Sea and will let you choose from playing a pirate, naval officer or an adventurer. The game will be released next year but you can apply for beta test right now. The game looks great at this point and will probably look even better when it's polished and ready for release.
