Heather – you have nothing to worry about.
My wife is very tolerant (and even often supportive) of my arcade collecting habit. In the past year, my collection has swelled to include 5 pinball machines (Funhouse, Black Knight 2000, Star Trek: The Next Generation, Flight 2000, Eight Ball Deluxe) and two video games (a MAME cabinet and Operation: Thunderbolt). Along the way, there have been several more that have been in and out. As long as I self-police my collection size and expense, I’m reasonably sure that I can continue to enjoy my wife’s support.
I’m here to tell you now..
Heather, you have nothing to worry about. I’m nowhere close to this guy.. yet..

This guy has literally dozens of video games and pins in his complete arcade conversion – including blacklight carpet and change machines.
I’m drooling – but I’m guessing there would be mutiny if I tried this..
