A simple way of playing trivia....
On Wikipedia, you can find tons of ranked lists, ie (country by population, city by GDP etc.) My friends and I found one that ranks every country in the world by how much alcohol the average person consumes each year. One of us ran the game by proposing 2 countries to go head-to-head. Then everyone would vote who they think drinks more. Then we would tally the scores for each question. The loser after 10 rounds would take a shot. The tie breaker was always to have each person pick a country they think has the highest alcohol consumption. Higher consuming country wins.
Another way to play is to score on differential. This way if someone chooses Pakistan (0.0) over Ireland (13.7). At the end of the game, they will have 14 (13.7 rounded) drinks.
Of course it doesn't NEED to be a drinking game. Simple punishments are just fine.
