I think hording games is when 75% or more don't work. Even working games can break down easily. For now, we have around 15, only about 10 working, or so games in our gameroom and in one weekend 5 more games died. Leaving us with only about 5 working games.
Also, a horde is when you have WAY too many games, cabinets, parts, etc., and NOTHING is for sale.
We never had a crane machine in the kitchen, but we have had a pinball machine, Arkanoid and Burgertime in there. Attached dining room had Frogger, Pole Position and Q*bert. And our den/computer room had Space Invaders Deluxe and Space Zap. Now that we have our addition just about totally finished, there are no games in the main house, (the garage, on the other hand is just about full).
I'm a horder and I have a problem. Someday, I will start going through all the non-working, non-complete crap and stripping and listing, someday...
