Fallout has never been totally tonally consistent or logically sound. Take the Three Families. Do you know how long they've been "rehabilitated"?
About 7 years. Benny was the guy who headed the transformation from the Mojave Boot-Riders to the Chairmen. This is all information that is kept fairly obscure from the player. Same with the Legion, which is
only 33 years old. Timelines are a bit too short imo. However, it works a hell of a lot better than the fucking Cabots. I refuse to ever let that dumb shit go. Gunners are a neat concept, though one could argue they are a knock off of the Boomers, they're still interesting. The Institute is completely redundant and tone breaking : why do we need yet another group of racially discriminated people and maniacal technocrats? Especially when they possess fucking teleportation and the ability to make perfect artificial life for no fucking reason? The Children of Atom would make a way more interesting faction, better than even the Hubologists. I'd even say the Meresti Family is a great concept, just executed terribly. I'm ok with a little wink-wink nudge-nudge kind of thing, like the Dunwich building or the occasional Alien encounter. I think it splashes in a little color and makes things interesting. But don't ever make that the focus. A lot of people enjoy Point Lookout because it played into Bethesda's strengths: environment and atmosphere. The story is almost always left on the wayside. I can't think of one person who seriously likes Mothership Zeta (or even Operation : Anchorage, though I feel this one is more tragic). Old World Blues is loved because its got fun writing and fun concepts, which again plays into Obsidians strengths. But even Obsidian sucked with their DLC (a lot of people dislike Dead Money for it's difficulty, Honest Hearts for its length, and Lonesome Road because of Ulysses). There needs to be a nice balance between the serious stuff and the wacky stuff. Obsidian blends the two together pretty well most of the time, while Bethesda just cranks them both up to extremes and doesn't really mix them together.
