These present an interesting question - should a few of these shows be considered "recycled" vs. remakes? Like HQ recycling the Video/Kiddio Village concept for Shenenigans? Don't want to get into a word war, but if there is only partial similarity to the original, couldn't something like it be considered "new"? Everybody recycles a good idea. If Bob Stewart learned anything from working at GT, he sure learned how to recycle a success!
And I do remember reading in a trade magazine that Barry-Enright was considering a 20 Questions revival. IIRC, Enright told me that then-employee Ron Greenberg was more for the idea than he was. Enright, who worked at WOR back in the days when 20Q was a radio show there, said he thought the format was too dull for today's audiences.
Seven Keys - with a two-player race up the game board, each trying to win keys for a single showcase of prizes - that I'd like. Have to iron out some details - but in one sense, the Joe Farrago Break The Bank with the clue screens and the electronic cards struck me as a Seven Keys clone already.
