Since everyone's already done base-game Fallout 4, I'd like to do Far Harbor.
The basic premise of the game remains the same. Big Island, mysterious fog, hardened locals, Arcadia serves as a place of refuge for either Synths or Cyborgs, ect., however a few main plot points are changed.
The Fog
The Fog was an incredibly interesting premise. Who isn't fascinated by a thick, poisonous fog that spews out monsters. Only problem is, 5 seconds in to Far Harbor, you're told its a "Radioactive Fog"
I mean, radiation isn't the only danger in the Fallout franchise, why not be creative like they did with the cloud of Dead Money, or in FO1 when Mutants were caused by FEV. Plus, why would an insignificant little island be nuked more than Los Angeles.
So rather than being told the Fog is radioactive, your simply told its a poisonous fog, and that the local guide, Old Longfellow has some kind of immunity to it. Old Longfellow is a ranger, who often spends days surviving out in the wilderness. His job is to hunt any Fog Creatures that get too close to Far Harbor. In return he's treated as the hero of the town.
In addition, there are no longer Fog Ghouls/Radstags(Perhaps replaced by Giant Bunnies or something silly) or Deathclaws on The Island. Since it's no longer radioactive, the first two make no sense, and since its across the ocean, Deathclaws don't seem like they could have reached the island. You also no longer have Trappers(Just generic raiders with themes), and Wolves are now a lot bigger. Also, the only Supermutant around is Erickson(Only intelligent because he was made from a Vault Dweller, not because of the fog), who fled the Commonwealth. Why would Supermutants care about The Island?
Staying in the fog too long will have different effects, as it contributes to invisible "Fog Points"., You will start off by getting a raspier voice(-1 to Charisma), then you will find you went through extreme bloating(A further -1 to charisma, -2 to Agility), then you'll find a decrease in muscle mass(-3 to Strength) and then death. If while travelling, any of your SPECIAL stats reach 0, you die. If however, you are on the quest to follow Longfellow, or simply have him as a companion, instead you'll find yourself in his cabin, and he'll tell you that you blacked out, and will give you 10 Fog Potions, a home-made concoction designed to keep away the effects of the fog.
You don't find out much about the Fog until Vim! Pop Soda
Vim! Pop Soda
Getting a new brand of soda was a cool touch, and the whole story with the factory was quite fun, only problem is its all pointless. None of it ties in to anything. They had pre-war stories just for the sake of having pre-war stories.
So here's my idea. As you enter the building, you notice that the main entrance is through a river, where there is a hole in the wall. You notice several smashed up distilling machines, presumably used to make Vim! Pop
You also see a door that appears to be locked down with a military grade terminal(Unhackable)
If you hack an Expert level terminal, you can download a Holotape of a meeting with someone from West-Tek, informing the CEO of Vim! Pop that he has a way to stop his company from being bought by Nuka Cola. He informs him of a project he was working on called the Pan Immunity Protection Virus, and how his research firm have abandoned it in favor of a genetic modification project. He claims that he wants to continue the original project on his own, and needs a few test subjects to work on it.
He then shares his ideas of letting out small concentrated amounts of a custom-made virus in to the atmosphere, while simultaneously adding tiny amounts of Pan-Immunity to Vim! Pop. Since the locals drink a lot of it, he claims that if they seem to not be showing visible signs of being infected with the virus, then he has successfully found a way of causing quick immunity to any new diseases.
He promises that in return for going along with the experiment, he will use his government contacts to make sure that Vim! is painted on several dozen suits of Power Armor over in Canada. Since people love soldiers, finding out that Vim! is a sponsor of the US Army will surely make it far more popular across the US.
Lastly, he warns the CEO not to pollute too much(May cause the local wildlife to grow in size over several generations), or not to change the dosage of Pan-Immunity(Only large enough doses cause proper immunity).
Far Harbor
The idea of hardy/suspicous islanders was an interesting one, however it kinda felt like it was one xenaphobic asshole, rather than the whole of Far Harbor having xenaphobia towards you.
Most of the Harbormen never trust you. Even when you help them, they ask you "How long are you staying here?" or "Will you be here long". You also occasionally get comments about how you have to look after yourself here, as they won't look after you when you're gone.
Old Longfellow is still as xenaphobic as the rest of them. He will only join you, because your a tough combatant and can help him patrol the wilderness. He will always treat you as a naive mainlander, and will never quite trust you. He will certainly never come back to the Commonwealth
In addition to this, Far Harbor doesn't have a currency. Instead a new form of the Barter system is brought back, and rather than ever being able to give caps to or get caps from them, you have to instead give them something of equal value.
You no longer get Settlement quests from Far Harbor. If settlements still exist in the re-write you have to find them yourself. Also, rather than being able to build Fog Condensers, you have to purchase them from Arcadia.
Lastly, if DIMA is executed, you no longer get the long scene where everyone you helped stands up to defend you, instead the Harbormen simply discuss whether to attack Arcadia, and decide not to due to not wanting to waste lives. They agree to stop trade with Arcadia, and will not hesitate to kill anyone they suspect of having connections with them(You will eventually find out they killed Brooks and Captain Avery). Also, if you travel with Nick, the boat arrives at a different location, and when you approach Far Harbor they will inform Nick that he's no longer allowed entry.
Also, if Kasumi is returned home before you deal with the Children of the Atom, you will find Far Harbor has been destroyed by them when you get back.
Children of the Atom
Replaced. These guys have become a stupid cliche anyway. Instead, you have the Children of the Fog. They appear different, have completely different sets of belief, ect.
Rather than living in a pre-war submarine, instead they live in a wooden village they built themselves.
They are far kinder than the Harbormen, and will happily greet you, and welcome you. They will all be glad you sought them out. There leader will tell you that they are centered around protecting the new eco-system the Island has. He claims that the life that grows around the island has formed its own eco-system, which is fragile, and by fighting off the fog(Which supports the local wildlife by acting as a cover for them) the Harbormen are damaging the life of the island, and that they should just allow the Fog to continue to envelop the island, so that nature can take its course. Of course, they also have beliefs about the Fog being a goddess, so its hard to take them seriously.
When you earn the trust of the Children of the Fog, they will let you drink from a "Holy Spring" within the village, that lets you see The Mother in the Fog(Like in the quest), but also gives you permenant immunity to the fog. There is also a Vim! Pop style distillery floating around in the spring. If you tell the people of Far Harbor about this spring, they will make a direct attack on the village, in order to get access to the spring, which you can either help them with, or defend the Children of the Fog(Turns Far Harbor Hostile)
Since obviously there are no longer nukes lying around, due to the Submarine no longer being in the game, there are now other ways to destroy settlements. Far Harbor is destroyed if you smash up the Fog Condensers, You can break several computers within Arcadia to create Electro-magnetic pulses to disable the Synths and Turrets, and if you have either a piece of wood/stone, or a Flaming Weapon, you can burn The Children of the Fog's village to the ground.
Lastly, if there leader is replaced with a Synth, you come back to hear about a lot of infighting amongst them, and many extremist believers who broke away from them, refusing to make peace with Far Harbor(Can come across hostile variants of them)
