I feel that anyone can play pinball in tournaments, but enthusiasts like most of us here would enjoy it the most.
Anyway, back to what I was talking about earlier...
I'm different from many other people. Because of how my brain works I acknowledge details but sometimes fail to see the big picture. I focused primarily on myself in the last post I made and I'm sorry about that.
The longevity of pinball really depends on who is playing it. If it's a kid who's around 6 - 10 years old they may lose attention quickly and go play a video game. Older people aren't much different but they may be willing to give pinball a try. Adults are the most likely people to play because of how often they see pinball machines in bars and restauraunts.
While I enjoy pinball as much as everyone else here, kids and teenagers should feel free to have different opinions and try not to think too much about my post.
