We play this one often((my nephew(age16)and I))when we don't have time to play a longer game. We often play for points in 5 game "Championships of the World".
By playing 5 game sessions and playing for points some of the "luck factor" is taken out. We also roll to see who makes the rules for each game in a session so the winner of the roll can pick a game that is to his advantage srategically.
The variants make the game more interesting and I recomend using them to add variety.
