I was thinking for the next installment you could make it so your party members interact and talk with each other. It would seem a lot more real if instead of a party that only talks to you, you had a party that interacts with each other. I'm not necessarily talking about big things. but maybe idle chatter or poking fun at one another. Maybe you could see a few of your party start to become friends or maybe they end up hating each other.
Then again. maybe I am the only one who thinks this.
