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.
The game looks good, but the story is just terrible. Connor is a terrible character. I liked the gameplay, but they added too much. The fun part about the previous ones was where stealth actually mattered and you had limited resources to work with. In this game unless you're supposed to not be seen it's better to just run in and kill everybody. Don't even get me started on the naval missions. It may be worth a rent, but do not buy it.
