When I was young, I was one of those kids who doodled Mario and Mega man levels (bosses too), though the real catalysts were Secret of Mana, Chrono Trigger and Lucas Arts point and click adventures. As trivial stories are in video games, people never merit the interactivity of story TELLING in video games. That paved the way for me developing story-focused games.
I especially like stories about limited parameters, a small number of locations, a small group of people. These are the kind of stories I like telling, I like telling them through a narrative that leads reader/player where their decisions have varied results. I also like occult and "forbidden knowledge" themes that can lead to horror and/or insanity.
