Pirates of the Burning Sea is an odd kettle of fish. It's pretty ugly and mediocre to look at for the most part, but it does have a certain rugged appeal to the presentation. The control system and style of combat is difficult to get to grips with and poorly explained, but rewarding nonetheless and worth a look. The quests too are flawed, proving dull for the most part but thrillingly epic if you want to get into the spirit of it all.
Pirates of the Burning Sea may be a little damaged by some flaws and contradictions in the game design, but the truth of the matter is that there's a little piece of eight buried somewhere inside and if you take the time to uncover it then you may well find yourself an MMO worthy of your attention for at least a few months.
