Quoted from Atomicboy:Take a look at what most people at pinside have in he their collection predominantly, or what they have on their wish list.
I think some of that is true but part of it is what people are exposed to. I've seen and played most every WPC title out there and a lot of the early solid state games. The same cannot be said for most pins prior to about 1979. If I'd ever seen an old EM Fireball or Atlantis, they would probably be in my wishlist too.
