Yes, back on topic. Thank you.
I will add "The Price Is Right" episode of Gameshow Marathon. While playing Hole in One (or Two), they edited out the whole "or Two" bit and the second (missed) putt. When it aired, all of the loyal friends and true figured that there were different rules for this special.
I'd like to count Celebrity Poker Showdown here, which production-wise felt more game-show-like than other poker programs. Hands that were largely inconsequential were edited, but the dealer position would noticeably be affected.
And just to comment on a point that I was going to make before the thread tailspun, regarding the editing/canning bad endgames on Million Dollar Password. I understand the outrage as a game show purist. But as an entry in network primetime, from which non-reality-style game shows have been largely absent for nearly a decade, the program had a six-episode order to fill. If you have an end game that bombs, that is 8% of your entire season, on which you are trying sell a second season. (The 8% includes the preceding front game as well.) Trashing a half episode for poor gameplay was a necessity in this case.
