...this is why I shouldn't post first thing in the morning, I didn't answer the full question. Duh! Anyway, thanks to my brother's love of drama and now-husband and friends were constantly running D&D and White Wolf games I was able to immerse myself in myths constantly. My mother encouraged it because I was learning and reading, which she loved. I myself ran a Changeling: The Dreaming game for quite a while because the stories the books drew upon reinspired my love of Fae and Celtic myths.
I decided to app into FG because I loved the concept, and while my initials characters, minus Raven, were pretty failworthy once I rediscovered my love of Greek myths I felt a lot more comfortable. Thankfully, my love of reading and the joy of work downtime and access to wiki and theoi from work has helped a lot in reminding me of the random adventures my brother and I used to come up with before he grew up. I don't consider myself grown-up most of the time...
