The arcade business is not available in the single-player version of the game.
This additional requirement serves as a gateway to owning an arcade, which is essential for setting up The Diamond Casino Heist. After this cutscene, you can proceed to buy an arcade from their in-game phones. During this meeting, a cutscene featuring Lester Crest and Georgina Cheng will play. To buy an arcade in Grand Theft Auto V, you need to meet with Lester Crest at Mirror Park first.
