They are already mostly gone except in a few places in tokyo and the obvious geek dens like Akihabara. And they are all smoking which means you get cigarette smell amd feel dirty after no time. No thanks.
As a non-smoker who regularly frequented arcades, I welcome this change. Sadly since COVID I've avoided going out entirely, and am not surprised that the industry is dying. I agree with trzy in a separate thread: experiences like The Void[2] which are impossible to have at home are the only thing I can see driving people back to arcades.
