And it ruins the experience too. I remember when I used to go to arcades, and there were games that paid out tickets, and games that didn't. Playing games that didn't pay out felt like a "waste", because I couldn't get tickets. ...Even though they were likely more fun, and the tickets weren't worth all that much in the real world.
I had enough rounds of almost enough tickets, come back next time and the prize is gone, or has inflated to twice the tickets to know that playing ticket games was a waste. So I spent my tokens on the fun games. I do like the free game mechanic in pinball though, you can earn one with skill, and there's a chance of a free game by luck with match at the end. Although, both of those are manipulated: modern machines will drop the replay score when it's not hit, and match is set by the operator to a percentage, that may or may not be the 10% it appears it should be.
