*Warning* possible spoilers ahead
+Excellent platforming based puzzles. These are usually pretty simple to work out once you realise most of them have only one path but when you consider how they work as a whole they are pretty ingenious and will challenge you're platforming skills and timing.
+Great atmosphere and art direction. The Persian setting is unique and rarely done. Even in 2014 this game looks excellent. The character models haven't aged well but the environments have for sure.
+Ability to rewind time and use it in battle is an excellent idea
+First person view allows you to offset the terrible camera
+Varied enemies force you to engage combat in different ways
+The Prince. Although it happens infrequently, when the Prince does chime in it's usually something humorous and entertaining.
-The camera is a pain whether you're doing platforming or you're in combat. During platforming the camera will frequently move into undesirable positions forcing you to guess what you're supposed to be doing next. In combat it does the same which quickly becomes tiresome when you're unable to see the enemy attacking you from behind. It also struggles hard when you're in tight spaces and the camera has to contend with walls :S
-You're companion is kinda useless and it feels as if you're partnership is a one way deal. During platforming she will stand there and let you do all the work aside from when she has to go through a few cracks or pull a few triggers (to Ubisoft's credit they use this as a point of humour which is much appreciated). In combat she is the same. The AI refuses to move from a certain position unless you stray too far from her which means that when there are multiple enemies attacking her she is essentially a sitting duck which wouldn't be too bad but she has very low health. Oh and her arrows can harm you. She killed me once when I had one enemy left to kill and a number of times her arrow has hit me stunning me for a number of enemies to take away my remaining health. Her voice actor is also very poor.
-Combat encounters take far too long on occasions. You would expect combat to last about a cpuple of minutes at the most but sometimes they take double that making those encounters tedious to go through.
-Fall heights are deceptive. There are essentially 3 fall heights. Twice you're height which the prince can handle. 2-3 times you're height the Prince will lose a bit of health. Anything above 3 times you're height and the Prince will die. This becomes incredible frustrating when you have what appears to be a manageable fall and yet the prince cant take it. What would have been useful is a more lenient falling system where you took larger damage rather than outright dying for higher drops.
-The story. It feels as though everything is rushed. You never get a chance at the beginning to digest what is actually going and then suddenly you're on this Grand Adventure. What's worse is that at no point aside from the end of the game is the story truly developed, which is a shame because the concept is excellent. There are points in which the subplot with you're companion is expanded but it feels so contrived especially since she is so damn unlikable.
=You're companion would be far more likeable if she was controllable. Frequently during the game there are situations only she can deal with like crawl into narrow spaces etc. I stand by my point that she is still useless as you tend to do 95% of the work but being able to control her would have enabled more complex puzzles and allowed there to be more varied
platforming challenges if creative enough. In combat it would allow you to experience a different combat style and allow you to better position her to reduce damage if you were primarily going to play as the Prince. I belieev this would also help you better engage with her as a character (although thevoice acting is still terrible)
=It would be nice to have a larger variety of sand based abilities to use.
=Controller support on PC would have made the game much more easier to control but as it is it's still very much playable.
Get the game if you enjoy excellent platforming and puzzles but pass if you're buying it for excellent combat or story.
