I simply love this game, the story and the characters! It is different and better than different games I tried (about same genre) and it doesn't get you bored at all, maybe annoyed against the villan, but that is ok.
The only problem for several people who wants to try it is the battle style, everytime you meet an enemy there is a battle, no kill stealt, but watching the ability and combos of the characters it is the best method.
