In Memoriam: Gary Gygax
* Blizzard Entertainment would like to dedicate the patch in memory of Gary Gygax. His work on D&D was an inspiration to us in many ways and helped spark our passion for creating games of our own. As avid D&D players and fellow game developers, we were all saddened by the news of his passing; we feel we’ve lost a true adventuring companion. Thanks for everything and farewell, Gary. You will be missed.
