when I hear about assassins creed I remember ubisoft's attemt to protect it from hackers. they made "revolutionary" defens system. it was sooo goood, sooo effective and strong that even original game versions were banned as fake...still hackers broke the system fast... later ubisof used "hacker patch" to unlock the game for the original versions owners... this defence system wont be used again...
anyway, game is said to be really good, saw earlyer version, how it is played... best way is PS or Xbox. but PC is possible as well.
