Preston Garvey of Fallout 4 is one of the most infamous characters in the game, but not because of his personality or history. It’s because of how obsessed he is with helping the settlements of the Commonwealth. The way he dishes out radiant quests that populate the Sole Survivor’s quest log drives players insane, especially when they have other matters to attend to. However, there’s a reason why Preston is so hellbent on saving settlements, and it’s tied to his backstory. Though it doesn’t make him less annoying, it certainly provides some important context.
