Every single WPC/WPC 95 game starting with T2 right up through the very end including pin2k was diamondplated whether the logo is on the playfield or not.

He must have come up with that rule after South Park as that had a video mode

Did they pull it out after the game initially came out? Perhaps removed it from later rom sets because I absolutely played it at multiple locations in the Chicago area when the game was put on test and then released.

No, it will give it to you once in a game.

All games will get dimples when they get played. You don't notice them after awhile because it will even out from being dimpled everywhere.

If I am remembering correctly, any game that used a buy-in goes in Officers club. Grand Champion and Honor Roll are only for single game plays. Q's Continuum was scores > 10B and I can't recall if that included buy-ins or not.

That skill will come in handy sometimes when you have a ball cradled on the bottom flipper and need to make a shot with another ball on the upper flipper on this and many other games.

On the WMS games there was two sets of optos on the flipper opto board, one for the lower flipper and one for the upper. Pressing the button only part way in only triggered the upper opto so only the lower flipper flipped. I'm sure the Stern setup is pretty much the same, I haven't actually looked in either of my two Stern games but since the behavior is the same I'm sure the hardware is as well.
