Also, what the hell was up with you losing all knowledge of how to do stuff at the beginning of the game? Did the Old Man hit you over the head until you suffered total amnesia?
I enjoyed most of the game, but I didn't honestly do the assassinations unless I got bored. I explored the cities and killed guards. Eventually, I managed to (somehow) finish the prereq quests, so I went off and killed the guy in my way. What I hated was that as soon as the guy took a knife to the throat, every guard in the city instantly knew who killed him, so when I had lost the guards surrounding him or killed them, and I was casually strolling through the streets, fifty guards would pop out of nowhere. It might have been nice if the Templars got harder to kill as the game went on (At first I had to kick them off of rooves to have a slight chance, but later on I could just do those annoying little quick kills). It also would have been nice to have a lot more things to do while wandering around, instead of just massacring guards by the dozen.
On a side note, anyone else lure the guards over to where the entrance to the bureau was, then kill them above the closed entrance? When you killed them all, it opened up, and their corpses fell into extremely interesting positions. One guy's leg was through his chest, and made a 270 degree angle with his other leg.
