If back in Japan (Not sure if other Asian countries had them.) I would love to see a pachinko machine or two. And as another said, even though I personally am not much of a gambler, just having them there made the world seem that much more real.
In fact just running past or someone coming or going from the arcade and I could "hear" the machines, just made me feel that much closer to the game. Just a little disappointed there were so few games or real interactions in it.
