I went and counted
(because I wanted to know) Over the past twelve years (starting in October 1994)...

I have written 10 and co-written 3 tabletop adventures for Gaming conventions.

I have written 32 and co-written 2 live-action adventures for Gaming conventions.

I have designed and run four games at cons which don't fit into the above categories ("Dungeon Bash", "Dungeon Bash 2", "Surrogates" and "Gangwar.")

Of those 51, 7 games have been run by me more than once for a total of 56 slots at conventions or games meets in three countries (Ireland, England and Scotland.) My games have been run by other people in England, Taiwan and Poland that I am aware of. One of my games has been run as an online event on a MU*.

I have written a card game ("Biomorphic Internet Monster Kids.") I have written a public domain expansion for a role-playing game ("Demon: The Temptation.") I have half-written a role-playing game system and background ("Caineforce.")

I have failed to arrive with the goods for four conventions. I have never made any money from the games I have written.

There's an exercise in egotism for ya - As well as some home truth. At the current rate, I figure I'll have written by 100th scenario by 2012.
