So I went back and watched the cutscenes on pc to find like for like scenes. Seems like they redid a lot of the texture work and lighting in AC2. Some quick and dirty comparisons.
With faces that move like that I can't imagine rebuilding the models and reusing the animation data would go over well. >_> Add these comparisons to the OP?
