Revelations ends Ezio's story, continues Altair's and ends it, and Desmond's background cleared up, set up to end.
Presentation: A story that keeps you interested, and with an ending that hasn't satisfied AC gamers since the original; and like the original, it's open for the sequel all players know is just over the horizon.
Gameplay: Bombs are added to the equation making the game feel more like Splinter Cell. While bombs will only be used on occasion, bomb making isn't very interesting or fun. Everything from Brotherhood makes a return including recruiting and sending the assassins on missions to later upgrade them. The only exception and major change is the tower defense game where you protect your assassin den from attacking Templars by placing barricades, assassins on rooftops, and shooting Templars yourself.
Graphics: The best looking Assassin's Creed game yet, it's beautiful for a game that took only about a year to make, probably because it was in development by all Ubisoft developers everywhere.
Sound: The quality and realism of the entire soundtrack from voice-acting and footsteps to explosions and music, this game sounds phenomenal.
Lasting Appeal: Collectibles, trophies, and unique, fun, competitive multiplayer, you'll be in this game until Assassin's Creed III hits store shelves if not longer than that.
