All this discussion about cool sequel ideas reminded me of a sequel series I thought up of back in High School, ~5 years ago give or take.
The Premises for these are as follows -
Metal Gear Solid 6 : Sins of the Fathers
The destruction of The Patriots system left a power-vacuum.
A group of wealthy men from many major trades; arms manufacturing, technological engineering, medical studies, etc - formed a group of individuals known as The Founding Fathers.
The Founding Fathers have the goal of restoring The Patriots System to some capacity, with them being the ones who control the system and thus control World Trade and Global Politics. However, a few key individuals still exist that pose a threat, namely Raiden and Meryl.
To eliminate said threats, a program was put in place by an individual known as "Dr. Weaver". Weaver was a geneticist and had acquired the corpses of the handful of men who have once been known as Snake. By combining their DNA together, a recreation of the Les Enfants Terribles project would result in a new soldier. One born in confinement, given treatment to be raised to adulthood by the age of ten, and trained via VR sims and some field-sim action.
This clone has no name, and is simply codenamed as just Snake. He is told that he would be given his true name once he proves himself worthy enough to be as respected as the other Snakes. He has been told a twisted form of world history, where each Snake earned their name in history, given their true name. This is what motivates the Player Snake.
However, his first major target, Meryl; proves to be difficult as seeing her face triggers a flood of someone else's memories. He finds himself in a bunker with the body of a ten-year old surrounded by war. He is joined by a familiar old man named Solid and has a brief philosophical conversation about what it means to be a soldier. (You see, because he has the Direct DNA of the previous Snakes; he possesses pieces of their memories and personalities buried within his genes, similar to Assassin's Creed Genetic Memories that the Animus sifts through.)
When he awakens, he has questions and when they aren't answered; he breaks out of the facility and exfiltrates. Upon returning to The Founding Fathers, this Snake learns the truth from Dr. Weaver... who is actually Hideo Kojima himself! It turns out that Hideo was the father of the original Snake and has been trying to right the wrongs of his past. The Founding Fathers have 13 major agents, named after the original 13 states. Agent Rhode Island is a double agent and THE DAUGHTER of Revolver Ocelot!
To keep his cover within the Founding Fathers, Snake must falsify his field reports as he scours the globe for his "targets". Some lives must be taken, but others can be spared. Meeting past characters of importance will trigger those blackout states where Snake returns to The Bunker dream to have debates with the previous snakes that come before him, until finally conversing with all of them. You would see this Snake grow from his childish inner self and learn to be an independent man. Then you will have to finally make the choice to strike against the Founding Fathers.
Extract with Hideo "Dr. Weaver" Kojima as you attempt to escape the Founding Fathers' compound, killing a few of the other State Agents that helped train you as mini-boss battles. Eventually you will find yourself en-route to an old yet familiar site in the seychelles sea... Mother Base Beta. And there will be an old man with a scar on his head to greet you... The Phantom of Big Boss ... Venom Snake.
The game would end with Snake passing out and entering a small coma... leading to a sequel.
Metal Gear Solid 7 : The Serpentine Legacy
Snake finds himself dreaming in the Bunker once again, now Venom Snake has joined the group. Meeting with a one of the men that made up his very being caused Snake to lapse into a coma and learn more about what the history of his "bloodline" was. This results in Snake learning about the events of every game and the convoluted secret history of the world.
Now knowing what The Founding Fathers were truly ushering in, and a tutorial section, Snake eventually wakes up... nine months after his defection. He learns that The Founding Fathers are still in working order, but now are trying harder to hide. Dr. Weaver is believed to be dead. Venom Snake explains that even though he was supposed to die in Outer Heaven, he was saved by an unlikely friend : Quiet! She found someone who could remove her throat, preventing her from speaking and the virus from spreading beyond the larynx. Though now modern tech allows her to talk once more, although robotically.
Snake now understands what must be done in order to save the world from falling into another threat like The Patriots System : The Founding Fathers MUST be eliminated. Mother Base Beta has received some upgrades since we last saw it in MGSV, and serves as our missions HUB. Working with what remains of MSF that hid on the platform, Snake will venture out on missions to aqquire intel on the locations of The Founding Fathers and their State Agent Operatives. New Hampshire and South Carolina are already dealt with, now all that is left is the remainder of the states.
However, a new threat is revealed. Like with the original Les Enfants Terribles project, the surrogate mother was to have octuplets. Unlike LET, they were all allowed to be birthed. However, many had defects or undesirable traits. The result was that these inferior offspring were put in stasis to be used as spare parts should the primary clone, Snake; be injured and wounded. What is better than organs that would not be rejected by the patient?
Since his violent departure from The Founding Fathers, these seven siblings were given extensive VR training and then let out of stasis. Their goal is to take down their rogue brother, however; they have also not been told the whole story. Many of them have been convinced that the key to fixing their defects was held within the perfect specimen.
The Sibling Rivalry Boss Battles are :
Garden Snake = A Snake who is resistant to toxins and uses that to his advantage.
Copperhead Snake = One who is essentially a cyborg ninja and the Copperhead is a reference to his mostly metal body. He actually wants to kill you and ruin your corpse, believing his cyborg body to be superior and wanting to remain superior to his siblings
Rattle Snake = Baby-like features, small, yet agile and cunning.
Viper Snake = A snake who is essentially a recreation of The Fear from MGS3, using shadows and poisoned bolts to slow you and eventually kill you.
Titanoboa Snake = A behemoth of a man who is basically Sloth from Fullmetal Alchemist : powerful yet dim witted.
Feathered Snake = A defect makes him a sniper specialist, but up close and personal; his frail body makes him easily killed.
Mamba Snake = A snake that has only a few minor defects, and has the personality of Liquid Snake.
The 10 Mini-Boss HVTs are the remainder of the State Agent Operators.
The 8 Founding Father's are of course targets to be taken down, some lesser battles while others being fights that involve Metal Gears themselves, as is the namesake of the series.
Eventually, the Snake you play as will have enough dialogues with his mental projections of his predecessors. He will learn that their true names are not Naked, Solid, Liquid, Solidus, or Venom; but actually Jack, David, Eli, George, and Logan. He will begin to ask himself what should he name himself as. And by the time of the third time you fight Mamba Snake; he is actually convinced to join you in your attempt to stop The Founding Fathers, proving influential in the final battle; at the cost of his left arm.
The story ends with Player Snake finally "earning his name" from the last of The Founding Fathers : Patriot Snake. A name that he rejects and says that he has chosen his own name : Seth.
Seth then has the choice to kill the Final Founding Father, or let Mamba Snake do it. Either way, The Founding Fathers is finished, and the world can actually start to rebuilding without being controlled from the shadows.
Seth is told by Hideo Kojima that all of his sons, both Jack and his clone "brothers", lived lives filled with war. Only for a couple years before his death, did David know peace from the battlefield. Now it is up to both Seth and Mamba to live out their lives in peace. Seth agrees, seeing the world can now return to what it was before The Philosophers intervened : a world of Free Will.
Meanwhile, Mamba Snake ventures off. Sure he and his brother have good relations, but he still feels the call to the battlefield and wants to find out who he really is (DLC bait to have him go through a similar experience as Seth and choose a name for himself : being Vincent. Plus, this could be used to tie up any loose ends by story finale, such as HVT States Agents that still live IF their optional missions weren't dealt with by players.)
Metal Gear Rising 2 : Redemptions
Pretty much a telling of the story that was planned and teased at the end of the original Metal Gear Rising : Revengeance, HOWEVER... it has added tweaks to reference and lead the story into the events of Metal Gear Solid 6 : Sins of the Fathers. Plus, offers a bonus DLC loyalty package by letting you play through MGS6 and MGS7 missions that featured Raiden from his perspective, allowing players to have more fun cutting and slicing as a Cyborg Ninja.
Whaddya guys think? Am I a worthy successor to Hideo Kojima himself? (Jeez that sounds like I have an Ego. I'm only asking if it sounds like something Hideo himself would make.) You see the trick is to know how the original writer thinks. I put myself into the seat of Hideo and ask "How would Hideo Kojima himself try to continue the story past MGS4 if he chose to? It has to be something that if I presented it, he would stamp it with his seal of approval."
Good thing I have a great memory and can remember it after all of these years. Perhaps I will pitch this to both Hideo and Konami?
