Complete Monster: The Vizier first betrays the Maharajah by killing the gatekeeper, allowing the Persian army to take the city. The Persian King Sharaman is in turn betrayed when in the Palace of the Sultan of Azad, the Vizier tricks the Prince into unlocking the Sands of Time from the Hourglass causing them to spread across the city and turn the population into sand monsters. When the Prince rewinds time all the way back before the sack of the city to warns princess Farah about the imminent betrayal, the Vizier plots to kill them both and tell the Maharajah that his daughter has been killed by the son of his enemy.
Demonic Spiders: The blue spear enemies that are immune to vault attacks (unless you vault off of a wall instead of them), and the sword enemies that are immune to vault attacks and have a sweeping attack that goes underneath the Prince's guard to damage him anyway. Both of these enemies are also the only ones besides the two bosses capable of countering the Prince's attacks.
Game Breaker: Except for the aforementioned enemies that are immune to it (knocking the Prince down when he attempt it,) vault attacks are very overpowered, often knocking down enemies in only two hits. And even with the two immune enemies, if you're next to a wall, you can pull it off anyway by rebounding off of the wall instead of the enemy. This will instantly knock them down, leaving them open for the finisher. The sequels nerfed it.
Even more of A Game Breaker is the fact that by changing one button that same vault move can instantly kill an enemy and collect it's sand without having to knock it down.
Goddamned Bats: Of the ledge kind. The game has swarms of bats that tend to show up when you're perched on a ledge hundreds of feet above ground. A couple of unlucky hits will have you falling. There are also vultures that attack you while you're climbing ledges, and at some points they literally hang around in the area and do not attack unless you start climbing or balancing on a precarious ledge.
Porting Disaster: The Windows version is reasonably well optimised and doesn't lack any features, but it is notoriously glitchy and crash-prone, in addition to being a pain in the ass to run. The infamously ill-fated run of the game at SGDQ 2015 highlights just how buggy it is.
That One Boss: The Sand King is one of the game's only two bosses and quite a few players would argue he is in fact the hardest one to beat, especially considering that you need to face him relatively early in the game.
The film provides examples of:
Alternative Character Interpretation: Given that King Sharaman apparently spends most of his time drinking, enjoying the company of his wives and studying religious scripture, how good of a King is he really? Considering that Nizam is implied to have always been the true power behind the throne, even though he's evil, how badly would he have ruled the Empire, when he's been basically doing that for decades?!
The reason Sharaman's reign was so prosperous is that the two brothers ruled together. Nizam was obviously the brains, while Sharaman was the face and Morality Chain. Take either of them out of the equasion and the kingdom would go to the dogs. It's a shame that Nizam never understood his importance.
Complete Monster: Nizam, the uncle of the hero Dastan, chafed at being in the shadow of his elder brother, the King. To remove himself from under the King's shadow, Nizam set his sights on the Dagger of Time and the Sands of Time, not caring of the horrors and chaos he could unleash on the world. Nizam brought about a battle with an innocent city, not remotely caring of the deaths of innocents, and arranged the death of his own brother while attempting to have his sons murdered. Revealing an utter contempt for the adopted low-born Dastan, Nizam revealed his true goal was to rewind time so he could undo this greatest error: once saving his brother's life when they were children.
Strangled by the Red String: Dastan and Tamina have the whole movie to slowly bond with each other, get into playful arguments and display plenty of Belligerent Sexual Tension. This seems to be one of the good things as their chemistry and the build up feels natural... But their First Kiss comes at the worst possible time. Right after violently dispatching the Big Bad's dragon.
