I often feel like I'm one of the only people on earth who liked this show. I will immediately concede that "Hot Potato" had a spectacularly horrid bonus round, why they went with that I'll never understand, as it was totally detached from the front game (not that that's always a bad thing). I will also concede that it's ripoff of "Family Feud" but let's note that "Hot Potato" actually admitted this in their own subtle way (note that Bill's rule speil included "What makes this game different...")
That said, it's a darn fine ripoff. First off, the questions they came up with were wonderful. It's not likely you're going to come in knowing America's 7 most-purchased dishes and drinks at diners and restaurants, but it's a nice test of common logic that could easily win a round if you just think about. It also posessed an element of strategy similar to "Split Second"...Come up with the most obvious answers and toss the potato to your opponents and leave them to come up with the more obscure answers. The "knocked out of the round" element and making the pass-play option available for an entire round of play made this a more strategic version of "Feud" (not better or worse version, just strategic). I thought it was a good game.
Memories of Hot Potato, since a few people have shared those: One that quickly comes to mind is an episode where the question was "What did people say was their favorite situation comedy currently on the air?" What makes this a classic is that either the team members weren't paying attention or just outright forgot the question, because late in the round, two contestants answer "Knots Landing" and "60 Minutes."
Also coming to mind is the "Boot Hill" bonus game question from the final civilian week, with Bill announcing five shows later during the first Celebrity week that due to the research department's error, the Coast Guard Rescue Team would get an additional $15,000. It comes to mind not just for being a feel-good moment, but also because the fellow who watched the show and spotted the error and called Barry & Enright Productions contacted me about 2 years ago to ask if I had any episode where Bill announced it; apparently, in the original run, NBC skipped a few episodes during the format change and never aired Bill's correction. So there's my antecdote.
