When I was 6 1/2, my brother brought home the white boxed set with the little grey Dungeons and Dragons books. I took them to my room and read them cover to cover.
The next morning at breakfast, I had 2 characters, Gandalf the Wizard and Frodo the Elf (I was loose with tradition back then).
I started my first game with friends when I was 10. I’ve been storytelling ever since.
I’ve played lots of systems, and I like best the ones that are rich but recede into the background. Some of the best games I’ve run have had no system at all. Soem of the best games I’ve played in have had simple systems but were all about character and story.
