@Ramuji: How did you do that? I didn't think it was out for a couple of weeks??
I live in Japan, where it was released on 6 December.
By the way, I finished the story in almost exactly 20hrs. But, I wasted some time by putzing around in town some. And, since I hadn't read the manual carefully, I was at rank 2 before I realized that there was a turbo button for the Schpeltiger, so I lost some time there, too.
I also got my assed kicked multiple times by a few of the higher-ranked assassins. So, a "better gamer" than me could probably finish it in significantly less time.
