I am hoping some chime in on the choice mods from GUN that should be considered. This is a standalone Merc Outfit mod is that will also be featured in the upcoming Fallout: London mod. I am sure others here have a massive amount of mods for their list.
The listed items are more corrections to the game (like ammo and armor mods etc) or cheats that I am just plain tired of playing (like mini games for lock pick or chasing down a Fusion Core to use my power armor for more than 10 minutes. the Special Patch), fan-made English translations and essential mods. Options to replace all humans with nothing/ferals/synths, rescue new settlers, spawn stalkers to grief you, dodge loot coughing nukes randomly launched at you. Rimworld: New Vegas adds several items and weapons from Fallout NewVegas and other. I don't have lots of companion or quest mods as I am mostly still exploring the base game. Fallout 4-76 transforms the Commonwealth into an open world with all areas unlocked and no human NPCs for a quest free land of scavenging opportunity. some of the above might even be outdated as I haven't really looked into those. If you are into the settlement *thang* then you need several mods for that like better settles, perhaps functional displays, place in red (so that you have more control over where you put things and not be blocked) etc.
