Difficulty/Fallout 3

Difficulty is a modifiable in-game setting

Overview
Fallout 3 has five difficulty settings: Very Easy, Easy, Normal, Hard and Very Hard. Difficulty modifies damage dealt to enemies and damage dealt to the player; lower settings decrease damage received and increase damage dealt, while higher levels increase damage received and decrease damage dealt.

Difficulty also modifies the overall amount of XP gained. Lower difficulties grant less XP, while higher difficulties grant more XP.
