Last Story has so much potential. So much more you can do with the combat, the story, and making the world more open. Pandora's tower is sort of built for the wiimote, i'm not really sure how you would do it without using the wiimote as the main controller or drastically changing the game. Pandora's tower did a good job exploring what you could do with the wiimote with fighting and puzzles, i feel like a sequel is not necessary.
