The lifespan of an arcade machine depends on several critical factors, including the quality of its components, regular maintenance, and the environment in which it operates. High-quality parts, such as durable joysticks, buttons, and monitors, significantly extend the machine's longevity. Proper maintenance, like cleaning, lubrication, and timely repairs, prevents wear and tear. Environmental conditions, such as humidity and temperature control, also play a vital role in preserving the machine. Additionally, the frequency of use and the care taken by operators or owners can impact its durability. By addressing these factors, arcade machines can remain functional and enjoyable for decades.
