Players created a character by choosing one of the three races, and one of three professions: Warrior, Trader or Explorer. Characters gained three types of experience: Combat experience was gained through fighting and completing combat jobs (being incapacitated resulted in "EXP Debt" and the character would only receive half of the normal experience until the debt was repaid), Trade experience was gained from selling loot, by building items and by taking trade jobs, and Exploration experience was gained from visiting navigation points and exploration jobs. In general each system had a number of "nav points". Visiting a nav point for the first time gave a certain amount of exploration experience. After a nav point was visited, it appeared on the "radar" when the player was in the system.
