This weekend I had the same thought. I usually play newer machines but I have a started really enjoy paragon. The pinball museum that I go to also has some ems. I started to play drop-a-card, A single player 9999 limit game. It seemed easy to simply knock down the cards (drop targets), but when I noticed that bumpers and other lanes changed from 10 to 100 points when lit, the game was simple but very challenging. An hour later I was still trying to beat my best score even it had the smallest flippers I had ever seen.
Now, I’m trying to figure how I can fit on more pin in my room.
