Technical quality at its best, sub-par gameplay.
One thing spoiled everything, right at the begining: this is not a RPG, like many sites said, not even an "Fantasy Action Adventure", it's a platform game, much like "Pitfall: The Lost Expedition" for the XB, not that I don't like platformers, but I was mislead.
The good points: art - very good, big bright sprites, cool & fluid movements, enough charecter diversification, the Rare's "elements thing" is very well achieved - for instance, the water movement and looks is briliant.
its sound - a good balance between epic and calm soundtrack, that actually works - for instance, the "Shadow Troll" soundtrack part really gets one into the game, very imersive.
The bad points: gameplay - plain, not free-roaming, nor strictly scripted (wich can aslo be a good thing, I don't go into that "let's do just this thing now!"), but this is neither, and flops.
value - little sense of reward/achievement (a bit saved by the 600 points one will get when going through the game). It has some hi-scores achievements but it's somewhat a lunacy to do 30000000 os so in the water temple...(!), so many, or most, will skip this and just do the 600 (why DEV's don't take a look at the marvelous achivement concept made by Infinity Ward/Activision in CoD2? those 1000 tasted real good, it gave me a real sense of "beating the game").
So a little bit above average game, mainly for its technical standards, but lacks a sense of empathy with the gamer. I'm concerned with Rare, PDZ is worse than this.
