More info here...Some tidbits I dragged out of the crappy babelfish translation:
~ Each NPC will have its own personality...
~ You can take as much time as you want to build up your kingdom (So it's not timed like Pikmin 1...)
~ Your reputation/control over your people depends on how far you are willing to go to help them...For instance, your villagers can come to you with requests, and if you fulfill them they'll obviously be happy with how you are doing your job...
