After some browsing, i began to wonder about endgames that have been adapted into shows of their own, I know of three that you can say were taken from successful endgames
the Super match format was turned into Family Feud
Chain Reaction's endgame became GO
The scrabble sprint became the clueword toss ups for the 1M chance of a lifetime
also the pricing game let em roll is adapted from the big showdown's endgame.
so my question is twofold, are there any other engames that were adpted into shows of their own and, are there any endgames (past or present) youd like to see made into shows of their own.
