Ubisoft is up to some classic online trickery in a promotion to unlock the world gameplay premiere of Assassin's Creed III. Sure, you could be satisfied with the 45 seconds or so of cinematics building up to it below, but if enough people like the game's Facebook page, the real action will be unleashed.
Of course, we can't make this kind of life-altering decision for you. If you've already liked the page, your job is done and your name will go down in the halls of history, but don't let the peer pressure get to you. Don't do it!
Actually, I really want to see some gameplay. Do it!
