What an amazing game!
The story is very intriguing. You play a prince of Persia. Your father attacks a maharaja's fortress, and you go off to raid the treasure room. You find a magic dagger, and an hourglass. You are then led to use the dagger to open the hourglass, and release the Sands of Time. The SOT steals your insanity, and turns you into undead sand zombies...very original!
You then have to undo what you did, and slay the greedy viserys.
The game is absolutely beautiful. The environments feel very real, and everything flows so naturally. Even the puzzles fit nicely and logically into the game.
The controls are fairly simple, and allow the prince to pull off all sorts of cool moves and acrobatic abilities.
The magic dagger also has the power to use the Sands of Time, to freeze, slow, or speed up time in order to help you. You can even reverse your own death if you have to!
