I like fallout, I like Bethesda, but there is a certain level of shine Bethesda is willing to put on fallout and it's far lower than elder scrolls. For instance I remember back when oblivion came out we all wanted werewolves, it didn't happen but we got shivering isles and when skyrim came out werewolves were standard. The elder scrolls modding community is larger but it lacks a lot of focus and ideas which are further divided by the will of the author. Because of this what you end up getting are either smaller mods you could do yourself or immense overhauls that kill your FPS and are likely to break you out of tonic. But with most fallout mods, things are in between and are usually lore friendly. As I see it everyone wants to make skyrim their personal fantasy game weather that be grim dark GOT, narnia, or dark souls, hell I made my skyrim into fallout 3 with a dwarven power armor and plasma gun. This is in contrast to fallout which every mod changes a ton of things tens to hundreds of thousands of people want changed and usually is lore friendly, because people who want to play fallout want to be IN the fallout universe as opposed to their own custom universe on the fallout engine.
