Well, one thing that would definitely need to be changed in arcades are the crane games. They actually need worthwhile prizes. The ones here are always dumb generic stuffed toys. That's not going to get people to play. Japan has a good system set up for theirs, with cool relevant prizes that are possible to win. I used to play with the UFO catches all the time, getting prices. And if you do poor enough, the workers there will actually help win them.
That would be good start. Maybe more rhythm based games would help as well. The taiko drum game as well as Mai-mai were popular while I was in Japan. Gun shooting games may help as well? It would be good if they didn't have awful games around, like... mobile style games made into arcades.
Dance my pretties!
