Fallout: New Vegas Traits

This page lists all traits

General information
Traits modify aspects of gameplay, granting a benefit in one area at the cost of hampering another. With the exception of Wild Wasteland, which has a less direct effect on gameplay, each trait modifies (and hampers) the Courier's statistics in some way; this can include Primary statistics, Derived statistics, or SPECIAL points and skills. During character creation the Courier may choose a maximum of two (with a minimum of none at all). The add-on Old World Blues makes it possible for them to re-pick the Courier's assigned traits.

Behind the scenes
As found within the game files, a medical history paper was to be filled in by the player from a texture of the actual paper; rather than a conventional menu. The paper does not mention the Wild Wasteland trait.
