I beat Assassin's Creed II (hello, 2009). I found around 70 of the feathers in my normal playthrough, and used a guide to get the rest. I want to 1000/1000 it since I did it with the first game, but some of those time-limit jumping puzzles in the assassin's tombs are a bitch. I don't know how long I'll keep at it. It was a pretty good game overall, and was better than the first one.
