I was never a D&D'er, but I did play the simpler (rule-wise), less regimented, but equally nerd-tastic Tunnel & Trolls in the early 80s. I started out as a spectator, sneakily laughing at the stupidity of people sat round a table rolling dice and pretending to be wizards and warriors.
But as winter rolled on and I ran out of student grant, cheap nights in started to look attractive. So before long though I was playing and having far more fun than I thought possible from something like that. With someone decent running a game (crucial factor!) it became an 'interactive fantasy novel' and could be incredibly rewarding. In fact it was running my own scenarios which eventually led me to try my hand at writing books.
Many years later I'm no closer to making any money from writing, but it's something which has given me a lot of pleasure over the years (everyone needs something to aim for even if they never get there!

, and I owe it all to GG indirectly.
Well, and Stephen Donaldson, whose novels captivated me at that time.
So thanks to GG for getting the ball... or should that be dice rolling.
Andrew McP... who still has his dice somewhere. Ok, I know exactly where, but I never use them any more, ok?
