This thread got me thinking of a lot of old games. Where I lived there were a couple of arcades within 30 minutes that had a lot of the popular games. But then there were drugstores, convenience stores and such that had one or two games, and often these were unusual and hard to find.
A drugstore near me had Tag Team Wrestling. Fun to play and watch:
Another store had Wacko, which I have only seen in the wild there and never again since:
I mentioned Tapper earlier, which was one of my all time favorites. Very challenging at the higher levels, and I was good at it. I liked games with unique controls, and Tapper had a standard joystick and two beer taps. I don’t think any other game used them:
One arcade near me had Super Pac Man, which again was the only place I ever saw it in the wild. I didn’t play it much, but I liked watching some of the sequel games that took something familiar and added new wrinkles.
