I recently finished it and here is my 2 cents...
The game is an adventure (not an rpg). The world itself is quite large and varied with plenty to see but hollow in substance and content, some nice ideas but not developed enough..As for story its in the realm of the usual amateurish stuff but who plays games for stories anyway? Graphically the game is very pretty, one of the best efforts on wii.. The music is nothing special save a couple songs.. What really brings it down is the action ( or lack thereof ).. There is one battle per area which u have to clear in a set time( 5 minutes?) Doesn't matter if you defeat all the monsters or not the battle will repeat itself over and over again. Some of the battles are actually very entertaining and its a shame there are so few of them.. I did not complete the game 100% but did a bunch..took me around 18 hrs to finish.. All in all i would recommend a weekend rent or eventually buy it when the price comes down as there isn't much to go back to.. Hope it helps..
