Just stick a few Pokemon characters on the backglass and all the kids will be playing pinball.
My boys used to play some but never anymore. Any other kids that have come over got excited at first, plays for a few minutes, and then never again. No use trying to explain any rules because they are just trying to keep the ball alive. Adults are the same and honestly I was the same when younger even with simpler games. It would be a waste of time and disaster trying to design pins for non pinheads. If you are going to be spending $7000-$12000 on a pin, you want the features to match the price.
