Pinball is a great hobby imo. You can spend time yourself tinkering on games or playing them. You can share them with others, play tournaments, or just play with others with a few beers. I lost my wife back in 2011 and pinball has been a nice escape. I don't have a lot of free time and pinball is nice where I can play for 5 minutes or work on them late at night when kids are in bed. A 19 year old full of energy and just getting out in the world may not understand all that. Things are different for 45+ years olds that been there and done that and just want some down time.
