From what I understand there will be a type of item called "gambits" that you can obtain that will allow different AI to be set for members who you aren't currently controlling. For instance, you could get a "black mage" gambit which would make the person you set it on constantly cast black magic on enemies you engage, or you could have a "warrior" gambit so they will attack engaged enemies. This is what I was told at least, I'm not sure if this will hold true in the actual final production copy of the game, seems about right to me though. In the demo, I heard a few townsfolk talk about "gambit" although I didn't get to use any in the portions I played... I guess the hours I spent on that thing still wasn't enough was it? bwahahahaha, I was too nice.
