Even though you're still flying through the air while dispatching minions left and right, Discovery subtly channels the essence of another Ubisoft classic -- Prince of Persia -- in its slick, 2D gameplay. It takes the stealthy swordplay of a simpler time and ramps it up with the otherworldly parkour that makes Assassin's Creed such a blast to play. Assassin's Creed II: Discovery received mixed reviews when it arrived on the Nintendo DS last November, and even though an iPhone version was concurrently in development, Ubisoft remained mum about it until this year. What were they up to all that time, I wonder? Building a whole new control system, it seems!"
