- One person, who is supposed to be neutral, controls the action and decides who gets the treasure.
- Each involves a significant amount of cursing.
- Each involves sitting around a large table for endless hours with the hygienically challenged waiting for something to happen.
- The participants of each activity have an endless supply of stories about something "interesting" that happened 3 years ago that makes no sense to anyone unless they happened to be sitting around that same table 3 years ago.
Those are just a few, feel free to add your own.
