Well, I'll name my favorite NBC ones in one post:
Assuming it's a game show (I don't see why it isn't), G.E. College Bowl would be first, then Celebrity Sweepstakes, followed by (not necessarily in order) Jeopardy! (the original version), Concentration (both versions), Sale of the Century (both of the three-player versions; I didn't like the couples one that much), High Rollers, Jackpot! (before they got rid of the riddles and the target number), Password Plus, Super Password, and Baffle (before it got incredibly easy - once a team got four puzzles in under ten seconds, that was pretty much it).
