IncGamers.com has posted a "first look" at Pirates of the Burning Sea. Editor Steven Macek had this to say in summary:
Whether you are a fan of MMOs or this is your first experience, 'Pirates' seems to be a good game. It is relatively easy to pick up and play and quite difficult to put down once you get started. If you can manage to meet up with some mates online, it is even more engaging. I feel comfortable recommending this game to anyone interested and I will post a more formal review once I get my sea-legs.
