A similar story here. I was into the game and started running a Minecraft server hosting company in high school (selling VPS'es with a Minecraft control panel, effectively). I ended up learning and doing the operations, maintenance, support, marketing, taxes--the usual jack-of-all trades of being a startup. My connections and experience there led directly to me joining another company, which has subsequently been acquired and landed me at Microsoft.
I wish more CS/programming classes, particularly pre-college, were game-oriented. A Java course I took in school had us writing a 'database' command line app that held fake enrollment information. Had that kind of thing been the only exposure to programming that I was given, I almost certainly would not have entered the field. But show someone like me a way to automate or expand something like Runescape or Minecraft? That, I'm interested in.
