Pirates of the Burning Sea is a pretty good MMO. The ship combat is like Sid Meier's Pirates. You can get into massive ship to ship combat battles. The non ship combat parts are pretty much standard MMO fare. The combat system is a little different so that the battles look more cinematic.
I played the free version. it's alot of fun for about the first ten minutes, then once the "wow I'm a pirate" feeling wears off, you realise it's a huge piece of crap.
