Not sure if this would be the best idea. Arcade games may be cool for the people that used to play with them in the past, but for the new generation they look dull.
The idea however, of using bitcoin for "arcade type games" is a good one though. No need for coins, just go to the game you want to play and swipe your phone and play!
Maybe there could even be an on blockchain ticket sytem, where instead of getting physical tickets for prizes, there are points awarded on the chain, which you can "sell" to get your prizes!
Well I think if kids are with their parents on the mall and they see the machines they are curious and want to play the games, in some malls there are still some arcade machines and I still see kids wanting to play when they see them, specially the machines that have not only joystick and buttons but have a driving wheel, or the moto racing ones.
Also a lot of adults like to play specially the moto ones which are really cool.
If Bitcoin can allow for cheaper prices I think it's a great business in the future.
