I'm not usually a luddite, but there are a good half dozen reasons why this just ain't right: Boing Boing - "Monopoly replaces play-money with fake credit-cards"!
Say no to rising toy credit card debt and go cash only (without even having to play-hock your little tin car!) Print your own free, real Monopoly money here at Monopoly.com!!
As the official website says, "The more money you have, the easier it is to own it all - so print your own! Just click on the image of the money you want to find a whole page-full."
Then you too can enjoy all the fun & games associated with rampant inflation!! Yay!! Enjoy!!!
