There's minimal increase in revenue for a well maintained game. Most casuals don't know or care. Pinball should cost $2.00 a play at the cost of today's equipment and labor to keep them running. Something has to give so you end up getting a dirty game at a budget price.
It's funny how someone would rather spend 50 cents to play four games on a dirty worn out broke ass machine then spend $2 for one game on a well maintained dialed in machine. I just don't understand it.
The fact they are that dirty shows that they're getting play so why would the operator care? Box is full of coins.
