Star Wars: Knights of the Old Republic/Experience

Main player characters gain experience from the following: Gaining experience results in gaining levels. Experience needed for next level = 1000 * current level:
 * Advancing quests
 * Killing enemies
 * Computer Use
 * Repair

Characters can gain levels up to maximum level 20. Party members gain 80% of the experience gained by the main player character, regardless of whether or not they are in the current selection: for example, upon becoming level 20 with 190,000 experience, party members have 152,000 experience (so they are only level 17 since 153,000 is needed for level 18).
