If you are curious about old arcade games and live around, or passing through Chicago, I highly recommend Galloping Ghost Arcade in Brookfield. Almost 900 arcade games going back to the 70s. They even have a coin-op Pong. All of the games are set to free play and it’s $25 to play all day long. They had every arcade game I could remember from my childhood at Aladdin’s Castle in Lincoln Mall. Even the really weird hologram Time Traveler game.
