||Desmond Miles has problems. There's a deep, dark secret, hidden in his genes... and some people will do anything to get it out. Assassin's Creed is the tale of Desmond, or, more specifically, the tale of the mysterious ancestral assassin hidden in his DNA You'll spend most of the game in the shoes of Altair, the aforementioned assassin, his great-great-great-great (well, you get the idea)-grandfather, one of the infamous Hashshashin who tried to drive the Crusaders out of holy lands. As you experience Altair's history, you'll periodically have a chance to find out more of what's going on in the present, slowly unlocking Desmond's own story along the way...Altair moves like a big cat, grace and restrained lethality evident in his movements. Uniquely, every one of those movements is perfectly in sync with the world around him. Altair doesn't have a generic climbing animation or a preset way to leap and grab things -- he moves like a real human, reaching out to grab whatever handhold happens to be convenient, wedging his toes into cracks, arching and contorting his body in response to the object he's climbing. When he hurtles through space, fingers stretching out for a ledge or beam that's just barely within reach, his body reacts like a real physical object, an actual body with mass and momentum. There's an incredible sense of physicality to his movements, a feeling that you're controlling a real person with a real sense of balance, not just a set of animations. At all times, Altair seems absolutely connected to his environment. He is pure joy to watch and control. Unfortunately, that makes the time you spend as Desmond all the more disappointing...Assassin's Creed, like its protagonist, has problems, not all of which are to be found in tacked on design elements. Still, in a game this ambitious, this impressive, it feels almost petty to complain too much about the rough spots. The nuisances, the looped dialog, the inane flag collecting and jarring 'present-day' sequences -- these are the teething pains of an infant franchise, not a sign of premature birth. It would be a finer experience without those nuisances, but they do little to diminish the sense of awe you feel when watching the sun rise over Jerusalem from atop the Dome of the Rock, drinking in the sight of the ancient city, and looking for your next victim.
