It's funny, I didn't really notice the similarities between Wheel and Million Dollar COAL until I got the home game of the latter. One thing I did like about Wheel's home game is that you could play the game alone, as when you chose a letter, it told you what positions the letter(s) on the board were located. If memory serves I think COAL also did that. I don't think I've ever owned the Deluxe version of Wheel, but one of my friends did. Oddly enough, he never wanted to play it, but that plastic wheel with the added on wedges... AWESOME.
I also would've liked to own the Scrabble TV game show home game. But I was much like that kid from The Middle, that tried to get people to play home games of game shows, and most of my family didn't want to play, but a few did just to humor me I guess.
I was stunned to see a home game of The Moment of Truth... who in their right mind would want to play that game, and how did the lie detector aspect work?
I never owned the Finders Keepers home game, but I saw it at stores. It basically had small boxes with small items hidden inside, and you had to pull out items until finding the item that the clue related to.... not as much fun as trashing your house!
