Arcade operators carefully evaluate several factors to determine when to replace a machine. Key considerations include usage frequency, maintenance costs, and revenue generation. High-traffic locations may wear out machines faster, requiring more frequent replacements. Operators also assess technological advancements—older machines may become obsolete if they can't compete with newer games. Regular maintenance logs help track performance decline, while profit margins indicate whether a machine remains financially viable. Ultimately, the decision balances cost, player demand, and market trends to maximize profitability and customer satisfaction.
