I've been into sci-fi/fantasy books my entire life, but never mythology in particular. One of the first roleplays I joined was a high-fantasy type, and the gods of that world were available as playable characters. I think that was probably what got me vaguely interested in mythology, though I never actively pursued said interest. FG itself, really, is what turned me on to mythology! My other IJ games were dying so I was browsing fantasy ads, and Forgotten Gods just kept showing up. So I joined, playing New Gods and folklore/historic figures at first, but I started reading all these awesome myths and decided "you know what, screw it, I need to get in on this action." And so I did! The end.
