fluffy Well it makes more sense than the Half-Life 2 Arcade machines they have there.
Twitch I never saw the appeal of this at all. I mean with pinball at least you get to like, move some paddles and stuff. My understanding of this is like, a ball falls around and you watch it. And Raymondo dances in the corner.
To check my facts I HTML'd over to wiki and found out that "..Because gambling for cash is illegal in Japan and Taiwan, balls won cannot be exchanged directly for cash in the parlor. Instead, the balls are exchanged for token prizes, which can then be taken outside and traded in for cash at a business that is nominally separate from the parlor, and may be run by organized crime"
