I think i'm in the minority here, but I really liked the last Prince of Persia. The new character annoyed me, as I'd become attached to the Sands of time Prince, but the gameplay was fun. And flowed better than some of the previous prince efforts. *Cough*Warrior Within.
All of that being said.
GOD it's good to have the Prince back. It's funny, while playing PoP 08', I didn't much miss the gameplay as I was satisfied wall running and ninjaing around. But let me be the one to say, running along a wall does not a prince make.
So much about this game brings you back to what really makes the Prince gameplay. Dodging traps, and spikes, figuring out ridiculous puzzles, and timing jumps with well crafted powers that only the prince can pull off.
In a story sense, I guess this game falls between sands of time and Warrior Within. Which now that I think about it, explains that amulet he has at the beginning of Warrior Within, that at the time, I never even bothered to question. (Correct me if i'm wrong, since I never actually beat WW, but I don't think they ever explain it).
This game has a nice God of War style leveling system, and moreover a nice GoW style mass enemy beat down. They tried to keep it akin to Sands of Time in the way that combat isn't very complicated. Instead they just upped the amount of enemies. Doesn't necessarily make it more difficult. But certainly more satisfying.
The biggest downfall of this game is the camera. It's the worst of any of the Prince games i've played. At any given time it only does about an 1/8 pan around the Prince, and in most cases, it's in a viewpoint that doesn't help you at all. It's terrible, it's frustrating, and I hate it.
The camera isn't enough to bring this game down for me, though. So far it's up there as one of my most satisfying purchases for my 360. Haven't finished it yet though. So who knows. they might entirely bugger it up for me.
