Quoted from IdahoRealtor:

I operate 3 pins where my league plays. It's an arcade, not a bar, which makes me more comfortable. As a collector first, I don't want my pins in a bar.
Anyway, I'm way in the hole. I'm maybe collecting $100/month per pin after the 50/50 split. Chump change when you factor in time, labor and cost of the pins ($5000+ each). And on months with break downs (very common) there's less revenue and parts bills.
And you may think "Hey, that's not so bad! 1 pin gets paid for every 2 years!" It's not that simple. Most titles get stale quickly and the revenue tails off, even when the pins are fully-working. You've got to swap them out to maintain the revenue, which is a pain. Moving pins in and out takes time. Bullet-proofing pins for location play takes time. Selling old titles and hunting for new titles takes time. Ugh!
I cannot recommend it for financial reasons, but I like knowing that people are enjoying my pins. Plus, bringing in fresh titles makes the league more fun.

Quoted from ercvacation:

Did they ever try to design the pins to give out tickets? Thats all the kids want and those are the only games my son will play. If the pins gave out tickets, it might attract more people. Just saying.
