Well I have been impressed with Square Enix's Final fantasy series and with this game.....I still am!
It's called an RPG, but its not what people might think. The game has very impressive art and I loved following the story line (makes a change from usually skipping video sequences and the like) It has many twists and turns that you cannot see coming and gives you alot of those 'ooooh so thats why' moments.
I loved the battle system, 'pins' (or you attacks) need to activated via the touch screen. Slashing or pressing at an empty, even shouting or blowing into the mic! And the dual battle system makes fights more intense and gives you something extra to deal with. Plus once youve completed the game theres extra things to do!
Well there aren't any down sides really to this game, the only thing i could possible say would be; because of the amount of pins there are and the ways of activating them, its a little confusing at the very start but you soon pick up what to do, and can pull of winning combinations by mixing different pins around
Oh one more thing, if you are going to play this game.....make sure theres a charger with you, as i can (most probably) asure you that you will on it for a long while, its addictive
