Starting at the start... my introduction to roleplaying came quite by chance care of a "Lucky Books Grab Bag". The Lucky Book Club is, or perhaps was, the New Zealand equivalent of Scholastic Books. Once every few months their thin, cheaply printed, catalog would come around and, if it was your birthday or something, you could get a book or two. If you parents had won the lottery or a magical goose had mysteriously shown up for a few days,then and only then could you get a coveted "Lucky Grab Bag".
The "Lucky Grab Bag" was in hindsight not quite so magical as it contained a "random" selection of books, which were probably under-selling or over-produced titles. In any case, the perception of the 10 year old me was that it was awesome and especially so on the occasion I was lucky enough to get one. Amongst the titles was the book that started it all, The Mystery of Chimney Rock by Edward Packard.
Setting aside my copy of The Star Wars Question and Answer Book about Space I dug into this weird book where you could literally choose your own adventure and it was amazing! I was instantly captivated by being able to move around in the story somewhat on my own terms make my own decisions. I've been hooked on the idea ever since.
From Choose Your Own Adventure titles I moved on to Steve Jackson and Ian Livingston's "Fighting Fantasy" series beginning with "The Warlock of Firetop Mountain". I enjoyed the dice rolling aspect of the combat and the harder edge. I particularly liked "The City of Thieves" and "The Forest of Doom" one that I did not enjoy was "Starship Traveller" and that, as it turned out, was to postpone my entrance into rpg's.
