The answer is : Not much.
Imagination has a Lingo board game - which looks - okay - I mean, how hard is this to do without a game? Don't you just need pen, paper, and a dictionary of 5 letter words?
Saw the new tabletop Wheel of Fortune up close from Irwin - it's okay as well - Big Wheel you spin which does not have individual dollar amounts, it just activates the LED display which shows a graphic of the dollar amount you spun...they claim it plays like the game, with tossups, million wedge, etc, but who knows. Still, its a nice table prop.
Irwin Toy is still pushing the table top Family Feud and Price games - no sign of the Million Dollar Password tabletop game.
Speaking of MDP, Endless has a regular and a DVD version - but both are still being developed - meaning, just a box, nothing more.
Oh, and there's a home version of Hole in the Wall , which comes with 100 thick pieces of styrofoam that has figures cut out... you have a player stand in the middle of the room making body movements to fit, as another person in the room advances to the player, holding up the foam cutout.
Just kidding. No, there isn't. Sorry.
