I've beaten this game more times than I should've and as far as I can tell it's a good game. I know, I know, it's old and its mechanics are bad, but Altaïr is such a great character, and even being repetitive, I had a lot of fun playing it. The main missions (assassinate the 9 targets) as well as the final fights are the gold of this game to me. Side quests sucks badly, but whatever. I've collected all flags but it's such a pain to guide ourselves based on maps on the internet. My recommendation is to play the game just for story and targets, don't bother doing all side quests. And please remember: Nothing is true; everything is permitted. (=
