At my place, every party or gathering lately turns into a pinball party. It is really satisfying to see the games being played and enjoyed, and seeing people who haven't played in 20 years if ever asking me about how to lock balls and commenting on how hard a particular ramp is or whatever.
All the kids like to play too. Sure, many of them will just start a 4-player games and then walk away after 2 balls, and flip like monkeys on speed, but whatever. they're not hurting anything. Plus there's always one or two that actually stick with it and puzzle out how to get a multiball going and start to really get it.
