I personally think if your under 18 years old, your parents decide that. If older then its your own choice if you actually can handle a violent game.

Fallout 4 ESRB Rating Summary: This is an action role-playing game in which players assume the role of a fallout shelter resident emerging from a post-apocalyptic world. As players traverse the open-world environment, they complete various mission objectives and use machine guns, machetes, lasers, and explosives to kill mutants and other human survivors. Battles are frenetic with realistic gunfire, explosions, and large blood-splatter effects; some attacks result in slow-motion dismemberment and decapitations. A handful of scenes depict chunks of flesh as well as severed heads and dismembered corpses. During the course of the game, players can consume a variety of fictional drugs (e.g., Buffout, Jet, Psycho) through the use of a menu; repeated use of these drugs leads to an addiction status and various negative effects for characters. The words “f**k,” “sh*t,” and “a*shole” are heard in the dialogue.[source]
