This document discusses Richard Bartle's Audience Segmentation model for classifying players into four types - Achievers, Explorers, Socializers, and Killers - based on what they find fun in games. It then lists popular games and asks the reader to identify which player types would be most appealed by each game based on its core mechanics and goals. The aim is to determine what kind of audience different games are designed for according to Bartle's framework.
