Follower Commentary Overhaul
The commentary you get from your various followers in Fallout 4 is pretty diverse. Not the case in Skyrim. Once you recruit a follower, they're actually pretty stale. FCO changes that.
Follower Commentary Overhaul adds a ton of new commentary for your followers so that they're less boring when you travel around the map. Specifically, there are over 1000 added lines of dialogue for the 18 vanilla followers in Skyrim.
Companions will start to feel unique, a far cry from their stiff personalities found in the vanilla version of the game.
A fantastic mod and one that would delight many console owners.
