I guess you’ve never suffered through a game played by six year olds, then!
I don't recall "suffering," but I've experienced the game with six-year-olds--when I played it with my friends and classmates at the age of six.
When I was about five and a half or six, my family liked to play a game called work-ups, in which the players take turns at playing batter, fielder, catcher and pitcher. As few as three could play, and the number of positions could be expanded with additional players. After a hit or an out, the batter would rotate to the field, then play catcher, then pitcher, then bat again. The winner was the one with the most hits.
I never was very good at baseball, but at the age of nine, I discovered bowling, which I have enjoyed ever since.
