Black Flag overcomes BOTH my complete indifference to Assassin's Creed games AND the clunky horror that has been previous pirate sailing games. Bravo Ubisoft!
I'm half way through this and I can't get enough of pirating and plundering. Great fun.
The story is exciting and interesting enough that they don't even need that silly ANIMUS device anymore. They should have cut the lame future story out completely.
My only other nitpicks. The controls are bit overwhelming at first, but they do a pretty solid job tutorializing. The city missions can get a little bit tedious and unrelated. Walking and running around the deck of a ship can be a bit frustrating, your guy is always jumping up on things or climbing the masts when you didn't want him to.
