I feel it is kind of sad to see old people in the casinos. They are mindless spending time. They don't even seem to enjoy it. There must be games that are more enjoyable than that. no skill needed, no creativity being developed.
I predict that current generations who have grown up with technology and video games are going to be much less interested in really dumb machines like this. But this is total armchair conjecture and I'm probably totally wrong.
