15. Assassin's Creed: Revelations

Developed by Ubisoft Montreal, Published by Ubisoft

Revelations continues the story of the war between the Templars and Assassins, this time tying together the separate tales of Desmond, Altair and Ezio. The single player is as engrossing as ever, and assassinating everyone from high-level targets to random civilians has never been more fun. What may come as a surprise is that the online multiplayer may be the best part.
