The Quake III Nation Player Character Guide has managed to round up a the known info on all the players in the game. While that doesn't consist of much for most of them, which simply say things like: "No Information available. Uses the 'xxxx' model," however the placeholders for the missing info offer the name, and in many cases the names of the model and skin used for each character, listing over 60(!) planned characters to be included with the game.
