Quoted from zarco:
All I've owned have had more than
usual PF wear. Paragon, Evil Knevil, KISS, Lost World as well as others. Was it a quality
issue with the PF's (and faded cabinets) or were they played more than others?
All the early Bally, Stern and Williams SS games usually have worn PF's. Arcades in 1977-85 were in their heyday and had a lot quarters dropped. A new 1978 Bally Playboy was $1475. 6,000 plays later @ .25 a game it was paid off and the rest was pure profit. Even at 150 plays a day in a busy location (there was one at my college lounge which had lines to play which was easily twice that) game was a real money maker.
Then after Bally made massive money on high volume titles like Eight Ball, Playboy, Paragon, SBM, Xenon and others, in 1980 particle board reared it's ugly head in cabinet construction starting with just the rear cabinet panels. Now in respect, they never realized we'd be anally restoring these games and stuck with swollen crap particle board.
