old games will always be rare, and in high demand. look at all bally williams games over ten years. one hundred percent increases and even more for almost every release from 1990 til 1998. I can't believe it, but it's true.

I don't think I'm alone in believing that the hobby will expand significanly, as it has done in the past four or five years, for at least ten more years. People are looking for a real, tangible entertainment experience. We have seen gamerooms and arcades explode back into our cities, which is awesome. The reason is obvious; Gen X moms and dads want to take their kids to these amusement spots to see what real gaming and amusement is, instead of letting them tune out into a console, tablet, or phone. Pinball and arcade games offers so much more than those other "App" type games on other platforms. there's no comparison.
also, as boomers retire and have more disposable income, and as GenXers make more money, there will be higher demand for new games and used games alike. Its impossible to believe that this demand will decrease in the next decade or more.
