Another idea that came up at BASFA last night was doing Hollywood Squares, although there is actually a problem with the physical set design for that one. Match Game can be done "flat" with all six panelists side by side -- we did that at MilPhil. It's better if you have a riser on which you can put an eight-foot table. Then you put three people behind that table and three more on a table at floor level in front, similar to the real show's set. Hollywood Squares needs a third level, which is trickier to build.
But if we could pull it off, we could even do the combined game that was tried for about one season that I sort of liked: the Match Game/Hollywood Squares Hour. This is complicated, and it's difficult enough getting six panelists, let alone nine, let alone writing another set of questions.
