The most annoying thing about Fallout 4 has finally been fixed, courtesy of modders. Thank god. If you've played Fallout 4, then you're probably well-acquainted with the nightmare that is Preston Garvey's endless settlement quests. It's always the same: you save one shitty settlement, only to be instantly tasked with defending another crappy settlement where no sane human being should ever live. If you happen to play Fallout 4 on PC, however, know this: things don't have to be this way. Really!
Introducing "Disable Minuteman Radiant Quests," by shad0wshayd3. It does exactly what it says on the tin. Per the mod description:
Have you ever wanted to travel across the Commonwealth and not have Preston breath down your neck about helping every settlement in the game three times a day from the same raider camp that was bothering them an hour ago? Well have I got the mod for you.
Mind, this does not mean the settlement quests go completely away. They're still there. The difference is, if you want to pursue the Minutemen settlement quests, you have to actively go to a settlement and take on quests from there. Additionally, depending on your settings, the quests don't clutter up your Quests tabs.
In practice, what this means is that you can talk to Preston without having him automatically saddle you with a new settlement quest. Instead, he just gives you his normal dialogue, followed by the sweet, sweet sound of silence.
