In an effort to bring this topic back to what it was supposed to be, I know my choice of classic PYL is obvious, but after burning some early 80's Joker episodes for someone who happened to be a friend of the contestant on the shows, I got a big soft spot growing for it again.
Price, would be great, but forget it. I fear even after Bob leaving us, his estate will probably hand some edict down blocking it or something.
Classic Squares still surprised me that it didn't fly. Eh, what can you do. I wouldn't mind it, though.
The main key, I think, is that no matter which of these it was, it would have to be something different from the classics on the sked now. So while other variations of Feud, Card and Pyramid might be nice, it wouldn't have the same punch (especially in Feud's case).
