In my opinion this seems like a great game but I do personally think this game is overhyped, to me it is just an : "American version of the assassin" just seems the same like the rest but better story.
Keep your Google Search skills ready because Assassin's Creed III is full of incidentals that made me wonder what in the world happened to Ubisoft's Tester/QA Team????
I had to replay at least three long missions within the Main Game due to bugs that made if impossible to continue unless you restart the mission. For instance, there's a mission where you play as Connor and you've been tasked by Haytham to steal clothes from a RedCoat. There's a glitch in the game where if you're detected while stealing the clothes, the rendezvous point where you're supposed to meet Haytham fails to move the game forward and you have to restart the mission all over again. This kind of issue happened not just from the Main Mission, but throughout side missions too (look up "lure bear glitch").
I love the Assassins Creed franchise, but it's getting old (same game style and dragging backstory with Desmond). I think part 4 just needs to end it already, IMHO.
