I found something cool.
The Bartle Test of Gamer Psychology is a series of questions and an accompanying scoring formula that classifies players of multiplayer online games (including MUDs and MMORPGs) into categories based on their gaming preferences. The test is based on the research of Richard Bartle and was organized into its first electronic form by Erwin Andreasen. Although the test has met with some criticism  for the dichotomous nature of its question-asking methodology, the test has been taken by a large number of computer game players. As of July 2007, the test had been taken by over 300,000 game players.
The result of the Bartle Test is the “Bartle Quotient,” which is calculated based on the answers to a series of 30 random questions in the test, and totals 200% across all categories, with no single category exceeding 100%. For example, a person may score “100% Killer, 50% Socializer, 50% Achiever, 0% Explorer,” which indicates a player who prefers fighting other players relative to any other area of interest. Scores are typically abbreviated by the first letter of each category, in order of the quotient. In the previous example, this result would be described as a “KSAE” result.
Achiever 33.33%, Explorer 93.33%, Killer 46.67%, Socializer 26.67%
EKAS players might be descibed as living by slogan: see the world, meet interesting people…and kill them. Immersion within the world is important to these players, because they love finding new things to explore–but they also enjoy the thrill of the hunt and finding other players within the world to fight.
That is so true.
