You Don't Say and I'll Bet had similar openings. The celebs would be introduced first, then the host says "My name is----, and the name of our show. ......., followed by an audience shot and an animated logo. The pilot, Show Me! also used a similar opening, all by same producer Ralph Andrews. You could argue that the YDS opening in itself was a ripoff of Password's opening where the celebs were introduced, then the host, then a shot of the audience with the game's title displayed.
With the GT shows, I think Card Sharks and Double Dare are the only shows that used a similar opening visually. Otherwise, GT usually tried to be unique with the way each show opens. I remember reading that the producers argued over the opening for Mindreaders. One argument was that with placing the celebs faces against a lighted square background looked too much like Match Game. However, they couldn't think of a better way to do it, so what we saw was the result.
