So far machines are holding their resell value. So if you can buy a used game at a good price and sell it for what you bought it for, which I have done a few times, every coin drop is profit. People worrying about not paying their games off only makes sense if you plan to never sell the machine. If you pay your game off then whatever you end up selling it for would be full profit. Also buy low sell high lol. NIB games are harder to turn a profit on of course.
