The Prince's final adventure of last gen came out the best with all barrels blazing.
The Bad: The game's really, really short; unlike Warrior Within, this one's linear.
The Prince of Persia lay dormant for quite some time. Sands of Time was his reawakening, and told of an evil Vizier tricking him into unleashing a curse upon the world. It was a wonderful game, but a little repetitive.
Warrior Within had the Prince going to the Isle of Time to try and stop that curse from ever spreading, so he wouldn't be destined to die. The Prince was no longer as honorable as he was in Sands of Time, and instead had grown angry and dark. These two versions of the same person seemed polar opposites, a rather large complaint from the second game. However, combat and game length were both improved upon.
Two Thrones sort of takes the best of both. The game is shorter than Warrior Within, but on the upside that takes away any backtracking. The Prince is now more of the honorable hero he must be to reclaim his home of Babylon. However, the Sands are unleashed once more, because the Prince changed time and unknowingly brought the Vizier back to life. The return of the Sands curses the Prince into taking two entities.
The Dark Prince is spiteful and enjoys death, in a similar way to the Prince of Warrior Within. This parallel, to me, is a brilliant combination and conclusion to the saga.
Warrior Within used a cast almost completely different from Sands of Time. Two Thrones uses that cast again, and that works out pretty well for it. Voice acting is again great, and you'll truly be glad you can play as the Prince and control the destiny of Babylon.
The combat system from Warrior Within, much improved over the original game's, is back in Two Thrones, and just as much fun. Picking up enemy weapons and using combos is again very helpful for changing the pacing.
Acrobatics, of course, have always been the highlight of the franchise. The Prince is still able to slide down tapestries, run along walls, and flip over bars as before, but he can now slide between walls, latch his knife into walls so he can keep running along, and more.
Chariot racing and controlling the Dark Prince are some more cool additions to the mix. Battling someone while going insanely fast down a tiny road is pretty fun stuff, and it works out the right way. The Dark Prince's weapons, and the need to move quickly (his health steadily decreases), are some more changes of pace. The Prince of Persia games did used to get repetitive, so these additions are crucial for the game's success.
The graphics and music, as ever, are extremely good, given that a PS2 has to be able to play the graphics. The cutscenes are gorgeous, of course, and the music fits the tone of the game, managing to combine rock and Middle Eastern sounds.
Plus, it's good to see this is the best game in the series, as it's the last in the trilogy. The undertaking of a video game trilogy is pretty big, especially for a third party developer. Ubisoft did this stuff right. The story ties things up better than you'd think it could be done.
Is it worth it? I think this whole trilogy is still worth it to this day. Sands of Time is a bit repetitive, Warrior Within is a bit dark, and Two Thrones is a tad too short for its own good, but none are bad. And the trilogy is even greater than its separate parts. Yes, I'd suggest it, regardless of what's coming for the Prince. Plus, it's cheap. That's one heck of a deal.
