Quoted from galore2112:

Haha, I’m just amazed how adults from 18 to 99+, with the sweet spot around 50 (judging by the popular themes (OMG BTTF faint!!!) and the looks of pinball enthusiasts at various events), behave when buying and selling a game.
Borderline crazy and quite immature.
Combine this with $5000 “gold leaf plated” toppers, the prevalent scalping to exploit the severe lack of patience and general greed, this community makes me feel like I entered the Twilight Zone LOL.

Quoted from trecemaneras:

As a fellow newb pinsider I can tell you there's a whole bingo card of standard newb activities that you need to complete before reaching the stage of blowing your top at a retailer you haven't done business with on behalf of a stranger, which is stage 5 or 6 I believe. For example, arguing passionately in a pricing thread is stage 1, then you'll need to leave enough theme suggestions in every manufacturer's "next pin" threads to accurately guess your age to within 5 years, then in a separate thread declaring you're an original theme guy whilst blithely tossing off a dozen nonsensical suggestions, it's all there in my post history. You'll notice I haven't yelled at mirco yet, which I will despite having never purchased anything from him, and that's because I still have a couple more newb moves to complete before I have clearance to do so.
