Watch the percentage deals though. On any coin-op not involving redemption, 50-50 is a minimum split.
True... but (my opinion) I don't think 50/50's a bad deal. Those games are expensive... and even though they may certainly pay themselves off eventually, the cost of maintenance has got to go up as they age and become less popular. To me, the 50% is worth being able to call someone else to deal with all the problems.
I used to have a pinball game in my place. It did pretty well, but (being mechanical), it always had one or two "things" that didn't work quite right. It probably could have done better, but fixing it every time it went down wasn't all that high on my list of priorities. So... there were days when it just sat there, turned off. The games I have now are much more reliable, and I can concentrate on selling popcorn... which I'm much better at!
