okay, i meant to post this last night but i was far too busy playing this awesome game. it's really good, guys. nothing compares to the feeling of your very first assassination (assuming you do it the quiet way). also; the Leap of Faith never gets any less satisfying....it's always amazing to suicide dive from eighty feet up and land safely in a pile of hay.
and the AI? not as big of an issue as everyone makes it out to be. as it turns out, the combat is pretty hard to get just right so the crappy AI doesn't really matter because you will still get knocked around a bit.
my only real problem with this game so far is the things that are and aren't considered suspicious. you can just be walking by a guard and he'll attack you but you can be running around on rooftop and getting in brawls and they won't think twice about it. but even that you get used to and becomes less of an issue with time.
also; this game is HUGE. not only are there three huge cities to explore (of which, i've explored only 2/9 of the total area) but there is a huge "wilderness" area that lies between the three main cities where you can ride horses and to more exploring etc. also, there is a fourth, smaller city where you start the game which is like the assassin headquarters.
there's no DLC, there's no online of any kind, no multiplayers, but don't think that this will be a short game to finish and be done with; there are hundreds of flags of different types strewn about the cities and outlying areas for you to collect (some of which are very well hidden). obviously, collecting them all gets you some achievments and has a positive effect on the game which i won't go into.
in summary: i think this game is alot of fun.
