There is a LOT of effort that goes into an AC game. Ubisoft has multiple studios around the world working on one game. Go look at the Credits of AC: Revelations, it's about 20 minutes long. They probably have enough man-power to do the same amount of work it would take an average studio about 4 or 5 years, if not more.
/Looking forward to Charles Dance as Emperor Emhyr.
