Just like Assassin's Creed, Shinryu. How many copies did they sell though? 
Amongst the inovations in PoP2008, there's the fact that you usually have bout 3 different paths u can take in each area to get to the shrine. Besides that, you can choose many different paths on the world map by activating one of the powers and going to one of the major areas in which you always choose the order. So i wouldn't say it's that redundant, regardless of the fact u always have to heal the area.
I didn't like the artwork graphics design alot either, Squirrely but it's not that bad once you get in the atmosphere.
I personally find the fact that you can talk to Elika at any given time and the lines the character have very entertaining.
Of course, it all depends on what kind of RPGs u like, maybe u're into the point & click 
Btw, the first day u got it? When was that rly?
