And if you're after something a little more serious, Curse points us to this slightly more academic gamer psychology test on GuildCafe. It's based on the Bartle Test, a famous test about 10 years old meant to categorize online game players into four different groups: Achievers, Explorers, Socializers, and Killers. The test was originally created for players of MUDs (if you remember those), but it's now been updated for MMORPG players. According to this test, I am an SAEK, which means I'm more interested in socializing and achieving than finding new places ingame and killing other players. Is that why my WoW Purity score is so low? Who knows.
