For me, my childhood is a blur full of fantasy. I watched my mom play LoZ, my dad had me watch Star Wars and some Star Trek, and my siblings and I watched a bunch of fantasy movies (even the really cheesy D&D movie). I read a bunch of shorter fantasy novels when I was little, including some of the tree house series, all of Narnia, and Terry Pratchett's The Wee Free Men. I didn't read Harry Potter until right after the first movie came out, and before that I had read a bunch of other books I can't even remember....
So, yeah....My mom and dad aren't huge nerds, but they sure have made me into one.
