I’ve always thought Whew! was the one. I loved Trivia Trap, but it’s kind of a guilty pleasure and has always seemed unpopular around here.Another great choice is Three on a Match. It’s mostly forgotten, and its scarcity is a plus for cult status. Its rules were idiosyncratic and changed over the run. The set and music were cool at the time and cool now because they’re dated. Its host was the finest ever and hosted more games than anyone, but only one huge hit.
