Sometimes you get progress and at times cheapening out backfires.
A lot of classic pins had their playfield slide along wooden rails for when you needed to rest it against the backbox. For some reason, Williams came up with a single hinge version around mid-80s, that caused the playfield to tilt so 1/3 of it was below the cabinet sides. Working on stuff around the back of the playfield was painful to a degree it was just easier to pull the whole playfield from the machine.
The sliding rails introduced in '92 was like a godsent for the people repairing pins. You could pull the playfield out and it'd rest on rails and you could lean it against the backbox at a sane height.
Naturally they tried to cheapen this out by getting rid of the nice sliding rail and just make it slide against grooves CNC'd into the cabinet wood, which was like worst of the two worlds. They must've gotten some feedback, as the next released game used the metal rails again!
Eagle-eyed viewers may notice the loose connector under Fish Tales' playfield. I shot that segment while shooting a video about its light matrix.
