A game is considered to be good if the Graphics, Sound, Control, Storyline is Good. Prince of Persia scores 10 out of 10 in all these factors, Sands of time has just redefined what a adventure game should be, Although the game is short but it better be short than total waste of money.
Music has its own authenticity(real persian or indian feel to it). And the storyline is one of the best that I have seen in a game.
Its not only hit the zombies game but you gotta do a lot more than that, you have various puzzles to solve within a certain specific time limit, and the different manuveurs that you can do is also good with the simplicity like cutting your nails. If you like adventure and FPS game then this is a must have. Its simply mindblowing.
