Hey Gary,
Wow, it feels strange to actually be talking to the forefather of D&D. It is most humble of you to take time to answer us mere gamers questions like this. I just wanted to say thanks.
I was wondering where some of the most classic aspects of D&D came from, and who came up with them. Was there one person who created most of the classic spells, like the Magic Missle? Also, what about the unique monsters, such as the Beholder?
Also, I realize this may be a touchy subject, so I'll understand if you don't want to answer, but have you played 3.0 at all? If so, what did you think?
Thanks for your time.
