Since they added a very few handful of things that were actually part of AC gameplay here and there, I am not so sure it's so clear cut.
And I would be lying if I said that I never ever hoped to see similar quality content than of AC added into the game. I was definitely not expecting AC2 since the beginning, especially after all that was stated by the devs on the subject, but heh...
I hope I don't get perpetual itchiness for forty days and forty nights, right, because I had the awful idea to look up to the classics, you know.
