At this point, Dave + Busters have proven that you can have a successful arcade.
Dave + Busters’ relies on two big factors at this point: a large restaurant with alcohol and a constant stream of new, trendy games.
DisneyQuest never relied heavily on food. Their food court looked really sad.
DisneyQuest also never had new games. Dave and Busters makes a big deal of getting new trendy games. They've advertised a Luigi’s Mansion game, a Star Wars VR game, and some other big, flashy games recently. Walk into any D + B and you won’t find a game not based on a recent movie or mobile app.
Universal could totally have a successful arcade. It just needs to be admission-free, have a restaurant, and have a stream of new games.
I’m not convinced Universal could keep an arcade up-to-date though. They’re not an arcade company. If a D+B or similar came into CW (please no, I like unique things!), it could be a success.
