I have never (unfortunately) played any of the old versions of the game, though I am told they're fantastic! However, I picked up the new one for PS3 and have been playing for a day or so now. I really like the acrobatic theme and the "smart-guy"-comments throughout the game. The combat system is maginificent, and unlike other games in this genre like Tomb Raider: Underworld, the camera does not flick about, ruining the experience.
On the negative side of this lovely mini-review, I'd say that though the in-game world is very beautiful, I still wonder why the developers decided not to take advantage of the PS3's awesome powers, but instead they made the environments, the prince and his new ally, Elika, very sketchy in appearance, like a rough cartoon. It has its own charm in that it is novel, but I still think it's a shame considering the possibilities.
Also, if anyone out there plays this, have you noticed how difficult it is to actually miss whatever you jumping towards? It strikes me as a bit too easy. (Luckily when I get my hands on Mirror's Edge that will most likely be countered
) The only time I fall is when I jump towards something that happened to be too far away
