These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Pin Ball
Crack is Cheaper: Both the machines themselves and to compete. To buy a brand new Star Trek Standard Edition from Stern would cost as much as buying a PlayStation 4 and 110 games. PAPA tournaments allow players as many attempts for the high scores on the machines as long as they are willing to keep paying the fees, which leads to arms races where players throw large amounts of money into the competition to one-up their rivals. Averted with IFPA tournaments, however, where each player gets a finite amount of tries for a fixed fee.
Dead Horse Genre: First, it was because video games were cheaper to maintain and took up less space at arcades. Later, as arcades died out, pinball machines all but disappeared. Of all the major pinball machine manufacturers such as Gottlieb, Bally, Williams, etc., only Stern Pinball remains today.
It could be argued that pinball has more of a Popularity Polynomial, as it is staging what appears to be somewhat of a revival in the last few years. Second-hand machine prices have surged. As an example, the value of Medieval Madness has gone from about $4,000-$5,000 in 2007 to over $7,000 in 2012. And as of 2013, a new pinball manufacturer, Jersey Jack Pinball, has sprouted up and released their first pinball, based on The Wizard of Oz.
