Board games are a very low-cost form of entertainment.
Years ago, I got the classic “Battleship” game at the local Goodwill for $2. My kids must have played it at least 100 times when they were young. A penny per person for each time they played. Compare that to the cost of going to the movies.
When my daughter went to college, she found some friends who liked to play board games. She learned of a game called “Settlers of Catan”. Because other people had purchased the other games that she’d played, she decided she would like to treat the group to the “Settlers of Catan” game. She asked if I’d get it for her for Christmas. It cost about $40 (after a coupon discount). Later I asked her about it and she told me her group had played it at least a few dozen times. Even without buying from Goodwill, it was still a great value. Assuming it takes 4 people a couple hours to play one game, that’s less than 20¢ for each person’s hour of play. And that’s just while she was in college. She still has the game, even after she’s graduated and started her first job in the big city. The only thing that’s a better value than that is a walk in the park.
