for the most part all those types love the game, and whether they're in it for the restoration or the competition, who am i to judge. more power to em all.
the only kind of hobbyist i disdain are the ones who don't want their games to get played by friends, family, and children. yes, kids double-flip. yes, sometimes they leave the game running with a 2 balls left to play. yes, sometimes they start a 4-player game on every machine and walk away. big deal. none of those things will hurt a pinball machine, and it takes like one minute to reset a half dozen pins. i'm happy to do it. you know why? because also, sometimes, they get really into it and a girl might spend all night trying to get to the Final Frontier or Black Hole Multiball or rescue Dorothy, and have to be dragged away at the end of the evening by her parents, and even as they're walking out the door, she wants to know when they can come back...
