I am currently 37 years old, I live in the Netherlands and started my first CoC scenario about halfway last year. I have been playing and running RPGs since 1992 - GURPS (in varying settings: fantasy, cyberpunk, starwars, pirates), Warhammer Fantasy, Over the Edge, Vampire: The Masquerade, Werewolf: The Apocalypse, Trinity, Vampire: The Dark Ages, Noir and KULT - but only got drawn into all stuff Lovecraftian in 2004, when I met my Mexican girlfriend who recommended Lovecraft's horror stories to me.
While I was checking bookstores for a collection of stories to my liking I remembered a copy of CoC (I think it was 5th edition) sitting practically unused on the bookshelf of a friend of mine. He had mentioned it occasionally to me but never got into running it with our RPG group. I borrowed the book, read it, and immediately ordered a copy of the 6th edition for myself. Since then I have been hooked.
I have too many interests to mention them all but generally each of them is more or less related to one of the following themes: old sci-fi and horror films, anthropology and archaeology esp. of Mesoamerica, drums, animals and natural history, photography, reading, RPGs.
I prefer horror and sci-fi over pure fantasy films, books and games.
I was introduced to BRP through CoC and am now waiting for the basic rulebook to arrive in the mail. The main reason for finally ordering it is that some of the upcoming supplements and settings for BRP seem very interesting for using with CoC.
Something I haven't seen yet but would definitely be interested in is a BRP supplement enabling you to add space travel to the classic 1920s setting of Call of Cthulhu and set scenarios on other planets of our solar system, as they were imagined in period sci-fi literature (For example making Venus a world of jungles and swamps in habited by intelligent amphibian/reptilian humanoids.)
