For me, it's Tomarken's "Wipeout" and then "The Joker's Wild", both versions with Barry/Cullen and with Finn.
With "Wipeout", as a kid, I enjoyed watching it because, well, it was a game show, and I loved Peter Tomarken. I also liked the running bonus round for some reason! But, I've watched a few episodes from the GameTV run a few years ago, and, while I haven't soured on Tomarken as a good host, I'm also not surprised at all that the show didn't last. It felt like so little game in an episode, but otherwise, if you didn't have much knowledge of a subject, you may as well have been picking numbers.
"The Joker's Wild" was a show I grew up with, specifically Finn's version, and I always liked it when I was younger. The weird dollar amounts on the wheels, tons of trivia questions, and frenetic pace scratched some kind of itch for me. I used to ask my mom to tape it for me when it aired at like 1 AM in first-run; that's how much I liked it. And, I liked it again when it was on USA in reruns. But, my god; watching it on YouTube many years later makes me think someone decided to take three separate game shows and mash them together in some sort of Franken-game that no one would stick with for more than an episode or two. That said, I don't think Finn was a bad host; he was just greatly constrained by the format.
Honorable mention: I loved the state lottery game shows when I was growing up ("Hoosier Millionaire", "Illinois Instant Riches", and "Megabucks Giveaway") and used to watch them every Saturday night, but feel they are so dull now when watching them in reruns on YouTube that I'm not surprised most of them have disappeared.
