My list is as follows:
* The B&E Q&A shows Joker's Wild (syndicated years), Bullseye & Tic Tac Dough.
Why? Because now that I watch them as an adult, I realize that 98% of those questions they asked are about as difficult, if not easier than most High School proficiency tests today. I was intrigued by those shows when they first aired because I was not yet a high school alumnus, thus the questions were challenging & on par with my schooling at the time. Now, when I look back at tapes and see a contestant mistake Hawaii for Nebraska in the Maps of States *visual* category, I realize how lazy the contestant coordinators were in finding good players.
When TJW first appeared on CBS, and I saw those rare eps. on GSN, those were game show quality questions, and that difficulty threshold should have stayed!
* Match Game '7X -- In the years of the blue set & the Star Wheel.
Why? Because that's when they started the era of heavy editing during the writing of the answers. I enjoy the banter during the WANK music -- and that, IMHO, is why MG got such a loyal following. Plus, it didn't give the play-at-home people much of a chance to come up with an answer or even to compare answers with other players in the room.
Yes, I know that a lot of that was necessary -- especially in the nighttime shows to get all of the game(s) in, but I still never liked the feeling that *all 6 celebs* could come up with, write out, and insert their answers into their slots in under 3 seconds.
