Cartoon Based on D20 Modern Setting
Despite rumblings of a new Dungeons and Dragons cartoon, the first Wizards of the Coast setting that will see production as a television show is apparently Urban Arcana. UA is one of the canned settings offered by Wizards of the Coast in its d20 Modern roleplaying game. Despite this announcement, it's not going to be in front of your eyes for some time. From the article: "...the Sci-Fi Channel and Fox Television Studios are developing a television series based on the Hasbro/Wizards of the Coast D20 MODERN campaign suppliment URBAN ARCANA for the '06-'07 season."
In fact, in 1990 there was a bad game show based on Monopoly.
