Ubisoft to Publish Puzzle Pirates
I've been a player for a year and a half, and the community is actually the most diverse I've ever seen in an online game. Most of the players are between 15 and 35, but there are a fair number of families that play too-- kids as young as 6 years (with parental permission of course) and parents as old as 50.
Because the game is so socially focused, you find that the most socially and politically adept people become the Captains, Kings, and Governors of the game. It's not at all like a traditional MMORPG where your guildmaster is the guy who logs in the most often and has the items with the highest numbers. Teamwork and community are the foundation of the game, so it naturally attracts those people most interested in those things.
