Steve Chenault of Troll Lord Games has just given word on the Troll Lord forums that original D&D publisher and co-creator Gary Gygax has died in his home, last night or this morning. Details are still sketchy and the forum site is not loading so well at the moment, but here you are. We’ll get you more when we can.
Update: CNet has more. It confirms heart problems as the cause of death; Gygax mentioned an inoperable heart condition in a 2006 interview. He is survived by his wife, six children, and seven grandchildren, as well as by all of us whose lives have been shaped in some way by his creation. He will be missed.
