Mr. Gygax:
Let me echo all the sentiments prevalent in these threads thanking you for your work in creating D&D!
Here's a question that might be a bit controversial: what do you think of D&D campaigns using deities worshipped in the contemporary "real" world? In early D&D publications there are references to saints (Cuthbert's mace, I believe?) and especially when Deities and Demigods came out, my friends and I all thought that an Arthurian flavored milieu would have to at least have some Christian (also pagan, naturally) elements to it. One of my D&D playing buddies made a joke about "Jesus Christ, Major Deity, 400 hit points, Lawful Good," etc. And of course there are some Oriental pantheons in DEities and Demigods. And in the DMG you have references to Arab/Muslim civilizations; for that matter, there's the whole thing about Assasins coming from the Arab world. Of course all that's been synthesized greatly in the fantasy literature. And yet, it wouldn't seem that hard to do to create a milieu where people worship Jesus, Mohammed, and so on.
