My recent interest in roleplaying games (RPG) led me to the Wizards of the Coast website:
Founded in 1990 by Peter Adkison, Wizards of the Coast rose to prominence in the hobby games market on the strength of the innovative and revolutionary trading card game (TCG) Magic: The Gathering, the first game of its kind and the progenitor of a worldwide phenomenon in gaming. In 1997, the company was granted an exclusive patent on trading card games and their method of play. 
Isn’t that madness?
Software and Business Process patents should go down the drain where they belong.
