With a game quality as good as this you can't go wrong at $24.99!
The world is very lively, it feels as if you weren't there things would just keep on going. The game has you assassinate 9 main targets in the cities of Acre, Jerusalem, and Damascus; however there is also the in between area called "The Kingdom" and Masyaf for you to explore.
The environment that you will be playing in looks incredible, oh and you see that loose board above the doorway? Oh my you can begin scaling the building using that! Almost every building can be climbed in some way on all 4 sides of it. My favorite part about the sound is being around a block of houses and still hearing someone give a speech to a large group of people and you can hearing them cheering.
Controls in this game are very friendly for new players, you can switch between weapons, running, and free-running very easily.
The selling point in this game for me was when I climbed to my first view point and took a look around the world that surrounded me, very beautiful.
I haven't played this game too much so I could not really see any flaws but I'm sure any flaw will be overshadowed by all of the wonderful things in Assassins Creed. The story is hard to walk away from, go pick this up if you already haven't I give Assassins Creed a 8/10.
