Karma

Karma is the reflection of choices made during games and how they are perceived by the inhabitants of the wasteland in Fallout 2, Fallout 3 and Fallout: New Vegas.

Background
A game mechanic measured in points and classified into three types including good, neutral, and evil. The player character always starts a new game with 0 Karma points, which is considered neutral. Wasteland inhabitants will behave differently toward the player character depending upon Karma, and it serves as a factor in unlocking certain dialogue options and game endings. Some games use both Karma and reputation as mechanics, while others use one or the other.

Gameplay

 * In Fallout 3, although Karma is measured in points, only associated status and titles appear.
 * In Fallout: New Vegas, both Karma and Reputation appear as game mechanics.
