Fallout 4 tells a story that is easy to follow along with and changes your experience based on your decision making in the game. In Fallout 4 you can make your own settlements and set up defenses against unwanted monsters such as Ghouls and Mutants, doing so will bring more people to your settlement for their own safety.

TL:DR
I recommend this game to anyone who likes Open World, Exploration, RPG's
