Been a big fan of Yu-Gi-Oh (strictly the actual card game) for a while now. I've collected them since I was really young. I only recently just got back into it and started playing seriously. (Before then, I hardly knew the "real" rules.) My friends and I now gather at our public library every week to play card games, which includes Yu-Gi-Oh and Magic: The Gathering (which was I was just introduced to a few months ago). Not only that, we take every chance we can get to play, which includes school. XD
I also have a few Pokemon cards I like to hang onto. So far I haven't met any other girl who's as into card games as I am, but I'm sure they exist. Somewhere...
