I was involved in a conversation with someone who I seem to be converting to Gameshowism (good thing!), and he came up with this question:
Say a show premieres with a set of rules and/or formatics. Later, the producers change the rules or tweak the format. Still later on, the producers go back to original Day One rules/formatics and stayed that way during the rest of the show's run...
Has there ever been a game show that usnsuccessfully did some tweaking but went 100% back to basics before it was cancelled?
