I guess we weren't too clear with that question and how we put it in the game. The guest that leads the lounge is determined by the choice you made at the end of Build 0.1, in which you pick someone classy or fun while looking at the fireplace. Classy means Kota arrives first and leads the lounge, fun means Luke does.
Thank you for your comment. It is useful for us in planning how choices will be structured going forward.
