Arcade operators carefully select game genres to create a balanced and profitable mix. They analyze player demographics, preferences, and spending habits to determine which games attract the most engagement. Popular genres like racing, fighting, and rhythm games often dominate, but niche titles can also draw dedicated crowds. Operators also consider space efficiency, maintenance costs, and revenue potential when curating their lineup. By testing new games and monitoring performance metrics, they continuously refine their selection to keep players entertained and revenue flowing. Data-driven decisions and adaptability are key to maintaining a successful arcade game mix.
