This is a very easy game to play. All you need is a bar, money for drinks, 2d6 and some friends.
All players tap their palms down on the table three times in an agreed rhythm then they immediately thrust out a finger, thumb or fist. Anyone who is not 'there' with the others is deemed to be asleep and takes no action that round.
What do the fingers, etc signify? You must agree that in advance. We started with index finger = attack, middle = build, ring = defend someone, pinkie = party. Then we added thumb = hunt, fist = earthquake stamp, palm up = make love not war.
What do you do? An attacker attacks a builder - 2d6 DARO each, winner takes a point; if there's a defender, the defender steps in and if the attacker wins the building is trashed. We decided a hunter has to roll doubles to catch something with 1d6 indicating the size - no one could attack a hunter.
We awarded 2 points for a successful hunt or party and 1 point for a successful attack, defend or build. If you beat someone with the peace tactic you got their points next time they scored as well as your own.
As soon as we got bored, we either replaced or added. If something wasn't being used or was too effective we replaced.
Someone has to keep score so you need a sober, responsible member of the group.
When does the game end? When someone buys a round - either because all glasses are empty and it's someone's turn or when someone is losing, gives up and chooses to buy a round to start a new game. Or whatever...
If people at other tables want to join in, they must buy a round.
