Just finished it. I feel like I finished it faster than all the other games, but I'm not sure. I wasn't playing it during a break, where I can play it nonstop and it potentially feels longer. Personally didn't like the storyline as much as the other games nor the ending as much. While the others introduced some legitimately new stuff, this didn't do so much at the end. Still enjoyable enough. Haven't completed all the Desmond stuff yet, though.
