"Pure" pinball? My idea of "pure"...
1) The machine needs be in complete working order.
2) You need be able to *hear* it.
3) "Pay to play" is necessary. Be that coin-op or tourney. No risk, no reward, right? Everything else is "practice." hahaha
Best thing to remember: Pinball doesn't have to be "pure" to be the greatest hands-on game of all time. Am I right?
