It'd be a shame to call Prince of Persia simply another series reboot. Truly great games of any genre assimilate proven ideas from other titles and introduce new ones. In this case, the new title combines strong platforming fundamentals, Assassin's Creed's open-world structure, and some of Okami's wonderful aesthetic flourishes. What it introduces to action games is something truly wonderful.
Since the Prince can't die, the pace and rhythm of gameplay is never lost, yet it still offers a challenge even for hardcore gamers. Elika is something of a semi-NPC, as you never fully control her, yet she's a hugely integral part of the game experience, from rescues to combat. With all of these ingredients -- both new and familiar -- mixed together, Prince of Persia is undoubtedly one of the year's finest games.
