I think I am possibly different to the average AC player in that I havent played really any of them other than the first few missions of syndicate and a few hours of brotherhood on the 360.
I own black flag and unity but have never played them.
So perhaps I am new enough to the series to be gripped by origins.
I appreciate how some of you feel though - I experience the exact same kimd of 'boredom' with Lego games! I have played every one through except the last couple of recent ones. I just cant face it anymore! Lol
