Apparently when I was younger, I used to play a game called “Garbage Truck” where I piled all the toys in the house on my bed and then it took forever (for my parents) to clean it up afterward. I imagine this game was very similar to “Train Station”. In this game, all the toys in the house form a giant pile with all the bedding in the house. The boys sit on top of the pile and boss us around from their vantage point. It is really cute watching them build it, but the cleanup is definitely not pleasant. I think this is what is called payback.
