It's fun AND beautiful
The game is rather easy, since you can never die. If you fall or miss your jump, your partner Elika will pull you back onto solid ground. If you start to lose in a battle, she will pull you to safety, knocking the enemy back. However, the enemy will regain some of it's lost health for doing so. To me, this is a really great option. Sometimes games are just meant to be fun, and not so much to provide a hardcore challange that will only end up frustrating.
Combat is fun and smooth, with great attack animations. You can attack with your sword, you can grab an enemy, and you can let Elika attack. You can combo all sorts of beautiful moves together to make for an awesome fight scene. None of the bad guys should really give you too much trouble, especially since right before you would "die", a button will pop up and if you press it in time you avoid the "final" blow, so that way Elika doesn't have to save you and the enemy's health stays where it's at.
The environments are great to look at. The world starts off all dark and dreary with corruption, but as you heal the lands, everything becomes bright and green and lush again.
Most of the time you'll have to go through an area twice, once to get to the fertile ground so you can heal it, and then you'll probably want to go through it again after it's been healed so you can collect all the Light Seeds lying around. You collect Light Seeds in order to "buy" special powers that Elika can use for platforming, which allows you to get to new areas.
Most of these powers are pretty simple and fun, with two of them basically doing the same thing and jumping you to the next power plate. Another, and my favorite, has you running along the walls and you have to avoid running into objects. However, my least favorite, is one where you fly through the levels and you have to avoid flying into objects. Sometimes with the camera angle, it's just hard to tell whether you're supposed to go left or right to avoid a column or a wall or whatever.
I know a lot of people complain that the game is too easy, but like I said earlier, sometimes games are just meant to be FUN, not challanging. I'm certaintly not going to hold it against this great game for being too easy. It just made it more fun to not have to go into a menu and load a save game because you missed a jump or because you got killed by an enemy.
Prince of Persia is one of the best looking games and really shouldn't be missed.
