Beautiful games.
I love the electro mechanical pinballs too. I've always been fascinated with how they work and it's such a satisfying experience to play a game.
The power of the flippers as the ball rockets off them and the kickers/pops thumping the silver ball around, lights and bells going off and on, reels turning. All in a random pattern that will never be repeated when you play the next game. Each game is one of a kind.
My favorites are the woodrails. I really get a warm feeling that gives me joy when I see them.
