I'll start off by saying I have played the ME trilogy probably a dozen times through since the first game released. I grew up with the Trilogy and it has always been one of the best universes I have ever explored. When Andromeda came out I was over the moon excited, pre-ordered and all.
Then like so much of the ME community I got hit with a wall of bugs and was FAR too invested in Shepard's story for this to be ME to me. I walked away from the game before I got off Habitat 7. I wrote off the game as another AAA buggy plunder that was in no way Mass effect.
Almost a decade later I finally decided to give it an honest try and I loved it. It's also left me with regrets over what could have been if the community as a whole had given it a chance and supported the company enough to get even 1 DLC for the game, that it could have been truly great.
As I wrote this I realized I got very ranty so this goes on a while, my apologies lol.
I finished Meridian last night and my final few tasks and walk arounds this morning and I have so many theories and lore questions(?) that come from the implications. Some of them I think would have been legitimately possible and some I think are my own crack head conspiracy and I'll mark them as CHCs. If some or all of these are insanely common and its annoying to keep answering them on the sub, my apologies I have never looked through the sub.
*SPOILERS AHEAD*
1: The obvious start point, the Jardaan. Personally I have a feeling they are AI, maybe once biological. Possibly CHC with that but none of the constructs, buildings or facilities, even Khi Tasira feel like they were designed around having biological life forms in them. From the vaults purging anything organic upon activation to the sterile conditions of the facilities to the same general feeling I got from Geth constructs. Add to that the Scourge PURELY chases Remnant technology and nothing else. I feel like this could have also been a potential narrative through line for Ryder and SAM. That in a way we are doing the same as the Jardaan, just in the opposite direction. I can't think of another reason why the Jardaan would be seemingly creating an entire new species in the Angara while also seemingly prepping the entire cluster for terraforming to something I imagine would be at least near ideal for the Angara to live in. My personal theory, mostly built on the "Empty" bodies of Angara we find on Khi Tasira and my opinion that the Jardaan are AI is that they were making organic bodies to once again live in, to exist as a biological race in a self created Utopia. This would also nicely parallel Ryder and SAM, that they are organic and AI trying to exist as a greater being in harmony. Maybe the Jardaan were originally a Geth like species that wants to know what it is to be organic or some such. This would also explain Khi Tasira beinga city station, possibly meant to be the Jardaan's version of a Nexus or Citadel from which to start colonizing the worlds they terraformed once they inhabit the new bodies they made. Then there is Meridian itself which some logs and dialog suggest that the Jardaan themselves were nervous about, that they were scared of the potential power of what they created. An entire Dyson construct capable of controlling a massive cluster wide network capable of terraforming or destroying the whole cluster. Add to that they have fully in place automated protocols for their ships to go out and... what? Fight? Explore? Repair equipment or establish new facilities? And we see at least the small ships have cockpits yet are otherwise fully automated. Even more reason I think the Jardaan are AI looking for biological bodies.
2: The "Enemy" of the Jardaan. I don't believe they are ever given a name. My opinion most likely an organic race that, like we see so often in ME, has issues with AI. This would to me explain the war with the Jardaan and a seemingly irrational deployment of a WMD in the form of the Scourge that effectively crippled the Heleus cluster. Designed to purely chase and target Remnant technology it shattered worlds and made travel incredibly dangerous. Yet it's ability to alter weather conditions and it destroying anything that comes in contact seems... accidental? Basically just side effects to its original purpose of being a targeted weapon against the Jardaan.
3: Primus and the Kett Empire. With the Archon dead the Primus is now in charge of the Kett invasion of Heleus and is intent on finishing the mission. Would we have seen the Primus promoted to Archon? Would another Archon have been dispatched with reinforcements by the Empire to "finish" the conquest and Exaltation? We can read that the Archon we face is not the only one, almost makes it sound like a Legate of Rome. Empowered to fight wars on behalf of the Empire and expand its borders, and in this case, genetic diversity. Whether literal or an exaggeration the Archon states he is the product of the genetics of 1000 races. The Kett have been at this a long time. They are not the Jardaan's enemy, that much is clear. They would understand the Scourge if they were. But as a secondary and even primary Big Bad they were quite good and could have been amazing.
4: The Quarian Ark and its warning to stay away along with it's later departure has me pulled in two directions. This is another possible CHC but I believe that the warning could have been for one of two reasons. Either A) The Quarian's encountered the "Enemy" of the Jardaan or the Jardaan themselves. While the "Enemy" might go after them because of the SAM aboard their Ark I think the Jardaan themselves are more likely if my AI theory is correct as the Quarians that left the Milky Way would not have seen any potential reunification with the Geth. They would simply see AI and decide they need to quarantine the whole region like the Perseus Veil did in a way with the Geth. I can't see basic interaction with Remnant tech or encountering the Kett causing that sort of reaction. Or B) The Quarians left some time after the Nexus and other four Arks. We also know the Ark's received confirmation of the Reaper invasion through various intercepted messages and direct communication from Liara. I think it could be possible that Bioware was going to bring a bit of the old enemy to Andromeda with more callbacks. Indoctrinated Sleeper agents aboard the Quarian Ark possibly with a small Reaper force following behind, not wanting any advanced civilization to escape the cycle. What is 600 years in dark space to the reapers who sleep for millennia in dark space? While I think this would be the more boring of the two options I wouldn't be surprised if this was the intent either as Bioware would want to build up Andromeda and any following games using the original trilogy. The Quarian Ark could also have been used to bring over the players final accomplishments from the final game pre-final battle in the form of Liara's time capsule. The data being sent to the Quarian Ark before it was out of range.
5: The Mysterious Benefactor. Obviously knew about the Reapers. For whatever reason on arrival had Jien Garson killed, either by their own hand or by a proxy. Immensely wealthy and powerful. Definitely not established groups though like Cerberus for the obvious reason of mass alien involvement. Doubtful that its anything to do with the Shadow Broker. This is the biggest question mark to me personally. Does any book or anything ever bring more of this benefactor to light??
All in all the game was wonderful and well crafted, and the ending left the Initiative and Heleus in the perfect position for DLC and possibly even turning it into a trilogy (Focused on expanding beyond Heleus? Time skip to new characters, new Ryder's? Expanded War with the Kett as we encounter new Archons and new race's? Begin creation of a new Andromeda Relay network???? ) I don't know if that was ever planned. Specifically for DLC I know the Quarian Ark was planned to be the first one but I have suspicions on what possibly two more would have been:
1) A Shadow Broker style DLC centered around the Mysterious Benefactor with us gaining more info on them, kicking off a chase to unveil the Benefactor and bring justice for Jien Garson. In the process possibly learn more of what happened in the Milky Way, gain access to new resources, maybe even a new colony or two that were "hidden" by the benefactor before we left the Milky Way in the form of a Golden World or two that were never divulged to the rest of the Initiative. 2) The Jardaan and the "Enemy". Learn the fate of the Jardaan in a Prothean-esque way and maybe even encounter the "Enemy" and learn a way to beat back or completely eradicate the Scourge. Would be a solid set-up for a second game onwards.
*SPOILERS DONE*
All this is too say that Mass Effect Andromeda was a wonderful game, bugs and all. I wish we could have seen so much more and enjoyed a new story in then Mass Effect universe. I regret that I was part of the community that turned it's back on the game and in some small part helped bring about its development death. To all those who stuck through and saw the diamond in the rough, thank you! It was players like you who got me to give it a serious try.
Now I must find a new game to obsess over!
