Star Wars: Knights of The Old Republic (series) - Gameplay

Gameplay

The game's system is based on Wizards of the Coast's Star Wars Roleplaying Game, which is based on the d20 role-playing game system derived from the Third Edition Dungeons & Dragons rules. Combat is round-based; time is divided into discrete rounds, and combatants attack and react simultaneously. However, the number of actions a combatant may perform each round is limited. While each round's duration is a fixed short interval of real time, the player can configure the combat system to pause at specific events or at the end of each round.

The alignment system tracks actions and speech – from simple word choice to major plot decisions – to determine whether the player's character aligns with the light or dark side of the Force. In the first game, the player's speech and actions have no effect on their teammates. However, the player has influence over their companions in The Sith Lords, the player's actions determining not only what side the player is on, but their teammates as well. The influence the player has on another character can be minor, from converting a character from the dark side to the light, to something as major as teaching them the ways of the Jedi themselves. Influence can be lost, however, if the player makes an action inconsistent with past decisions, causing the player to pay very close attention before reacting in any way.
