If asked to describe myself, the only answer I could truthfully give is "A Gamer". Granted, even I argue that it is the right term to describe myself, but it's definitely the best fit.
I don't claim to be a hardcore gamer. Perhaps a heavy gamer, but not hardcore. The distinction is often a little fuzzy, but I view it in terms of intent. I play, because I enjoy playing. I don't play to be the best, because I know I never will be, and I don't play the same game constantly - I like to play a variety of games, and enjoy myself doing it. Granted, the occasional online game can be fun, and I get as competitive as anyone else - but when I lose, thats it. I don't blame my team, I just accept it.
Unfortunately, I'm not a strong reader, and so much of what I do read are comics and books based on video games. Part of this is because I'm single minded, but most of it is because it's the only way I can stay involved enough.
