I tried that on PC thought it was terrible, maybe I didn't give it enough time
I'm not saying it's the best game ever made, I liked the storylines in both the main and DLC parts.
Yes there are annoying gameparts that will frustrate you, but then again, no game is perfect.
Do have to say that it didn't live up to the hype Ubisoft generated for it, but it's a decent game.
Speaking of Ubisoft, I have yet to finish Assassins Creed Black Flag, but only because I want to explore the entire map before continuing with the storyline
