What it’s like running an arcade in 2015.
Tl;dr, take advantage of the nostalgia and legal drinking age of 30-somethings and turn it into a barcade, amirite?
Though, given what we mostly played in arcades Back In The Day were bemani games… er. Maybe not so much. Unless you could set the DDR machine into the floor somehow so there was no risk of falling off it and breaking your old nerd neck.
