These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Awesome Music: All of the games (as well as the movie) have truly remarkable music.
The entire soundtrack to Sands of Time, done by multi-instrumentalist Stuart Chatwood with extra help from session musicians. Glad to know his experience with the whole Mideastern-rock fusion thing from his days in The Tea Party was put to very good use.
Special attention should be given to the PC/Xbox360/Playstation 3 Forgotten Sandssoundtrack as well. Wow...
Contested Sequel/Sophomore Slump: Warrior Within. You'll find either fans of the first game who hate it with passion or others who think this is the best in the series.
Game Breaker: In Sands, the wall-bounce can knock down-thus basically killing-just about any enemy. Any enemy it can't take care of is vulnerable to the vaulting attack. Nerfed in the sequels.
Genius Bonus: The Forgotten Sands contains several references to King Solomon that seem enormously out of place if you only know him from The Bible. However, in both Jewish and Islamic mythologies, Solomon was a powerful sorcerer. In The Sands of Time, the Prince twice mentions Rostam, a famous hero in Persian mythology.
Hilarious in Hindsight: In Warrior Within, when Shaddee is about to stab him in the back, the Prince rants that: "Where I come from we face our opponents. And if our enemy is unarmed we offer them a sword!" However the next game has the quick time events that allow you to kill your enemies from behind, making the Prince a huge hypocrite.
