Here's another thanks for answering all these questions.

When I first got into D&D in the 80's, Gygax was a name out of myth with no more reality than characters we were playing.
Thanks for putting a personality to the person. It's wonderful to see you have the same love of games after all these years.

If I have to append a question, here's one: What's with all the traps??

Take care, and don't let this take you too long from your work!

Again, quite welcome and my bit of fun 

As for the traps, we originally played dungeon crawls much of the time.
My dungeon levels were both an exploration/mapping problem to solve and a place for encounters.
As I would place perhaps 15 or so active encounters on a level of many passagerways and as many as 50 or so rooms, to keep things "interesting" I'd include various traps.
That became a de rigeur thing in general from around 1977 on.
Of course when combined with monsters and NPCs, traps add a degree of complexity to encounters too, so they are a handy tool.

That cover it?

Gary

(Thought of anything particularly good lately?)

Who can say, what with so many nasty traps having been included in movie serials that I used to watch at the theater on Saturday afternoons as a lad. I believe that I have thought most of them up on my own, but...

The Fantasy Life book contains a fairly extensive list of traps, many of which can be alaborated on. As for creating more if late, no. I spend such creative effort in figuring out ways of avoiding those Jim Ward puts into his MA game compaign :\

Cheers,
Gary
