- You send So Mi to the Moon to help her
- I send So Mi to the Moon to give Mr. Blue Eyes another toy
- We are not the same

Some details that I noticed about those endings:

- if you arrive to meet Songbird in the van quickly enough, when she complains about V being late, you can respond to her that you arrived as soon as she called, which makes her apologise by saying that it's her condition messing with her perception of time. This response is not available if you arrive some time after she called

- when you are driving with Songbird to the Spaceport and she has a conversation with V about trust, V has a unique response for each love interest that they started relationship with. What's crazier however is the fact that devs also included unique dialogue option for each love interest that you initiated relationship with, but didn't fully commit (like telling them that it won't work out after sex, which ends the romance path in some cases), with V using them as examples of people they care about which they ended up hurting in some way

- Cynthia does have a different reaction to V if you ended up ruining her marriage with Pepe, with her telling you how much you destroyed her life. She also have an extra comment if you approach her while wearing the workmen's uniform you receive from Songbird, with her assuming that V also took a second job (I think it only works if you didn't already talked with her before obtaining the uniform)

- that guy at 13:25 actually have a lot more going for him. He is another character you could run into back in the base game. He was the drunkard from Konpeki Plaza bar ranting about Hanako's arrival who you can calm down. If you talked to him back then, he will recognize you for that, but only if you didn't defeat Razor or did the quest with Samurai reunion before this point. Why Samurai reunion quest? Because if you did it, but didn't defeat Razor, this guy will recognize you from that concert and only if during the concert you picked the option to play the sick solo (which admittedly, everyone pick anyway). So yeah, they gave this one guy plenty of quite layered callbacks. To keep it simpler, the hierarchy of callbacks seems to be Razor>Samurai concert>Konpeki Plaza if you want to check it out

- after Songbird tells you that she lied to you, picking the response saying that you won't forgive her for that, changes V's final words to her, when you sending her to the Moon, to ones that feels a lot colder. Nice bit of consistency

- the names on the list of victims of the Orbital Air's attack are references to the game creators (the most noticeable for me was Pablo Sascobar being reference to Paweł Sasko). Also Jefferson Peralez supposed to have a different message to the victims if you told him the truth in Dream On quest, but it doesn't seem to display correctly in-game. In his paranoic state he supposed to write something like "Your strings were cut down too early".

- regarding Chang Hoon Nam, after his accident, you can send him to Nomads to make sure that Max Tac won't track him down. Later you will get an angry phone call from Wakako asking you about what happened to him. If I remember right, after sending him to Nomads, you can encounter Chang in Aldecaldos camp at some point. When talking to him about sending him to Nomads, V might reference one of the previously completed fixer gigs (Flight of The Cheetah) and tell him how he helped Hwangbo escape with Nomads assistance

- when it comes to Sandra, if you are Corpo, you can pressure her into sharing more details about why she needs this backdoor installed, with V figuring out that she's doing it for another client of her and someone really powerful, who will most benefit from access to the NCPD data bases, but Sandra refuses to give a name

- if you didn't do Stadium Love, but did the quest with Panam in which she delivers drugs to the 6th Street, Gunner will recognize V as Panam's friend

- you can call River to ask for help with obtaining informations about Max Tac convoy, although obviously given his position in the force, he is unable to do so, but still pretty nice that they included that. He has a different response depending on whether he is still part of the police force

I chose to betray SoMi at first because I didn't fully trust her and believed Reed could help her, but I saw her memories and granted her wish. My intuition told me Myers was no good.

Jesus... Mr. Blue Eyes entering G-Man territory with these appearances.

I'm not the only one who played that ending, without knowing what I was getting into, at 2 am? What a rush!

3:32 If you look closely at the scene where Alex is Sandevestan-ing Hansen, you can actually see her grab the knife when he tries to use it on her. So yeah looks like she took it.

Fun fact. If you have second hearth upgrade you will get a new animation if he finishes you off. You will block his last knife stab and push him away from yourself.

That MaxTac assassin at the Space Port was insane, I never imagined it.

I love that the old net is essentially a Sci-Fi version of Lovecraftian eldritch horror... These unknowable alien intelligences, where us mere mortals touching their minds is enough to drive one insane.

23:18 Everyone is responsible for their actions. Solely for THEIR actions, not from others'. The Orbital Air massacre is entirely on Myers' shoulders IMO.

I think you're really underselling just how good the Quantum Tuner is, especially now that a lot of Cyberware has been rebalanced to have shorter cooldown. For those who don't know; the Quantum Tuner is essentially a gas tank that can hold up to 60 seconds of "spare" cooldown. This cooldown will get dumped into any Cyberware that completely depletes its own cooldown, refreshing it for immediate reuse. This will happen as much as it needs to until the tank is empty, at which point, it will begin to refill itself automatically whenever you are not in combat. This can have incredible applications, as it essentially allows you to bank multiple consecutive uses of some of the most powerful Cyberware in the game. Berserk, Sandevistan, Overclock, it works for all of them. Better yet, effects that reduce cooldown such as perks and the Tuner's own passive effect will reduce how much "gas" is needed to fill up each piece of Cyberware. A Berserk with a 25 second cooldown, with the Tuner and the cooldown reduction perk, will have a cooldown of 17.5 seconds, meaning that a full Tuner will give you three spare back to back uses of Berserk in addition to the one use held in the Berserk itself. There are very, very few combat encounters that can't be cleared with 4 back to back Berserks.

It even works with things you might not expect it to, like Kerenzikovs and optical camo. Even better; with the Relic perk that lets you escape combat by activating camo, you can start filling the tank again, and it will continue to fill as long as you maintain stealth. The uses are so varied, it really makes sense to me why it's one of the only unique items in So Mi ending. It's that powerful.

It’s just the fact you see blue eyes in the killing moon and even mentioned by song herself, makes me believe sending her to the moon is canon along with V becoming legend and meeting blue eyes

The Guy recognizing V, at the space port, for winning the Final Fight, is also the same Guy who sits at the bar at Konpeki Plaza during the heist.
During my playthrough of Phantom liberty, I did not finish the "Beat the brat" quest line but did talk to him at the bar and he also recognized V and has some dialogue options.

FunFact: It is actually possible to spare Hansen. When he is on his knees you can wait until the time is over and loot him anyway. But it wont make much of a difference. You will just get a text from Mr. Hands shortly after telling you someone killt him in the hospital.

I betrayed SoMi because I thought she would never stop killing and betraying people in order to live. But killed her after I realized Myers would never let her go completely.

18:48 That is JJ Abram's seppuku blade. If you look on the other side of the blade, "The Rise of Skywalker" is engraved into it.

The most interesting part about siding with SoMi for me was that I was so invested into the mission, into helping her, I never considered that she could be lying, that she could betray V, and I have no idea why, when she tells you I was, Of course she lied how I did not see that, I felt so betrayed, I could not go through with it, I left her in the train and gave her up to Reed. I felt a bit stupid afterwards,  I feel like V being so desperate to find a cure, that they could not afford doubting her, I don't regret being naive, the experience was awesome, and it only works once

18:17 but ciri said she went to night city while sphere hopping when Geralt finally finds her in the witcher 3

I gave So Mi over after she revealed she wasnt going to help, i was more surprised Reed actually kept his word. Despite losing implant abilities.

People should realize that the neural matrix itself is more important than the stuff inside it, just like the relic is more important than the stuff inside,
All of them can create an era-defining tech, IMO, Somi went to the moon or V treated by the FIA are gave both MBE and FIA the tech they needed,

To FIA, Johnny wasn't that important to them, but getting their hands on relic is a great opportunity to research and potentially relaunch the Cynosure project.

To MBE, just like Alt mentioned (you can also find the mail inside the bunker's terminal): the human neural system is so rudimentary for AI beyond the blackwall, so they'll need to find another way to infiltrate the human world, and there's a shard mention that the bunker system was almost unhackable, not without outside AI help, but the hacking do happen, so is possible that the "MBEs" are trying to infiltrate the bunker to get their hands on document relate to the Cynosure project, so if MBE obtain the neural matrix, it could be a enhancement their ability to enter the human world.

BTW, the original Soul Killer was a neural matrix too, back when Cunningham still working on ITS, the company was tasked to design a neural matrix to contain and transfer an AI, but later Cunningham discovered this could be used on the human mind too, so this program was later been branded as soul killer
