is opening a new retro arcade viable

[nightshade]

I know theres hardly anything new for arcades in America unless its an anniversary edition or something specific for chuck e cheese or for the adults dave and busters

But I was thinking of opening a retro arcade in my cities new downtown section and was wondering are machines hard to get ? and where do you get them these days ?

All I see are licensed 80 (or more)in one cabinets and the like ........

I know I couldn't use MAME for it but yearts ago in Indianapolis Indiana I was in a arcade that used swipe cards and you bought time

so what ya think?
