Another kind of choice that has less often been made explicit in MMOs is choosing a source of power. For example, a pet could be magic-based (e.g., elemental), nature-based (e.g., wolf), or technology-based (e.g., mechanical droid). Demographic differences with these three hypothetical choices were interesting.

Male players were about 3 to 4 times more likely to prefer a technology source than female players, and female players were about twice as likely to prefer a nature source as male players. Preference for a magical was roughly comparable between male and female players. There was also an interesting age trend among the male players. Preference for technological sources decreased as a function of age.
