You have a few videogames and you really play them a lot, you became an expert of every detail of them: indication of autism / Asperger (narrow obsessions). (Starcraft 2 seems to be optimized for this.)

You have a lot of videogames and don't really care about getting good at them, you mostly just use them to "discover", to daydream about living in a fantasy world, you find it important that your character should fit into a role in the world without breaking character, such as not wear mismatching armor that would make him look funny: indication of schizoid personality (withdrawing from the world, rich internal life). (Elder Scrolls games seem to be optimized for this.)
