One thing that’s really fascinating about virtual worlds and MMOGs is the avatars that people choose and the relationship between their choice and their physical selves. It’s pretty easy to find statistics showing that gender bending is a pretty common practice (for example), but there’s not been a lot of research looking at people choices of character race and shape.
A while back, Nick Yee, a research at PARC, published some statistics he’d gathered during his PhD on the relationships between age and gender on player choices of race, alignment, and type of character class. Graphs and notes on those results are available here.
More recently, he’s published another set of results concerning player choices of character shape; that is, whether their character is relatively taller or shorter, how attractive they are, and so forth. These are pretty interesting results, though there’s nothing really surprising. What’s really interesting, though, is the graphs he’s produced looking at the relationship between preferences for different avatar archetypes and for different styles of play.
Anyway, if you’re at all interested in self representation or online games, go take a look. He publishes these results via a blog he keeps called ‘The Daedalus Project’ – it’s not particularly high traffic, but what he does post is well worth reading..
