For parties who have seen it all

Your party gets objectives. Afterwards the replay decides which of you have been lying.
Random your hero, 2 of you.
Kill a courier, 1 of you.
Play one of the ladies, all of you.
Win, and do what it asks, or the game never happened. Every game, all week.
A shared target for the party each week, a personal one every three days. Points, levels, a ranking.
A hidden pool of badges for the weird, the funny and the embarrassing. They pop on their own.
