Why Geth and Quarians won't be in Andromeda and why you should be ok with it.

I get that, but mostly I'm posting because people on twitter are whining "What about Geth?" "What about Quarians?"

It would make zero sense for them to come. 

Not all quarians think alike? Do all humans think alike?

Geth want to achieve their own future. How they do this may differ. They are not under control of the Reapers at all, if you remember, the majority of geth, the True Geth, rejected Sovereign. It was only the heretics that followed it and even then, Sovereign wasn't controlling them, they were worshipping it. So there's many possibilities. One of them might be a third faction splitting from the geth, one that wants to go on the Arks. They would be allowed to leave, just like the heretics were. Why would they want to leave? For the same reason as organics, they recognize the old machines will return and that geth can't claim their future if they're nonfunctional. A deal could be struck with the organics for assistance with the ark in return for passage and leaving the geth to their own devices once there. Indeed you could make a good case that all geth might be amenable as they are not particularly attached to Rannoch or anything in the Milky Way. Obviously, the bulk of them stay... or do they? Maybe the reason the quarians won so easily in ME3 before the Reapers showed up was because a large part of the geth had already left.

So no, it's not at all impossible or even unlikely that geth and quarians made the trip. In fact it's preferable as they are the best suited to actually run the arks. Geth because they're AI and can run things while the meatbags sleep, and quarians because they're the best suited to the nomad life. Of course Bioware may ignore this on some half-baked excuse but what else is new?

Some things doesn't seem to follow logic (and probably won't). We have no clue on plenty of things.
And just because some things don't follow logic doesn't mean even more things shouldn't.

I think there will still be a few quarians, because their vociferous fans would throw a fit if there weren't any. Besides, it isn't all that implausible that a small number could be recruited to be part of a unique experience like this one. There are always those few quarians who just don't feel as beholden to the Fleet as most, and others who could be swayed by the chance to work on those arks.

The Geth should not be involved at all, obviously. They are still "the enemy", at this point in history, having made peaceful contact with not a single organic, as of yet. There is no way they could possibly be involved in this project. (Legion tells us as much, and he is not mistaken. He is in regular contact with the consensus, and is the lone platform of "true Geth" beyond the Veil.) As of 2185, the Geth are known for two things: seizing Rannoch and attacking Eden Prime and the Citadel. Any non-hostile interaction, let alone an alliance, would be a massive, strange retcon that would cheapen the entire Rannoch storyline.

I am definitely okay with neither being present. I value story over fanboyism. If something shouldn't be there, I don't want it in the game. We will have to swallow a few pills to move the story to Andromeda, but we don't have to get stupid about everything.

I agree. I don't think Quarians have enough people to spare for this initiative. No way they'd weaken their fleet of both manpower and ships for some long shot jump to another galaxy. Geth... I just don't care about the Geth. Hopefully some species in Andromeda will fit their dynamics.

I think we'll see quarians, not a lot but some. Remember, there is a lot of prejudice against them, so I don't really see them being invited formally to come along. In the trilogy Tali makes a point of saying how some people never come back from their pilgrimages. And I could definitely see some quarians taking a chance on the AI program if it meant finding a better place for their people. After all, the Initiative is supposed to eventually become an entry point for the MW civilizations. Also, I'm sure there are quarians out there who like adventure. I think eventually they'll show something, but not now.

As for the geth, well... others have stated pretty good facts already. I like the geth, but at this particular time, it would make no sense for them to be in the game.

Speaking of who is with who.

Indeed quarians would make sense to be inside the Turian Ark because of the food.

But what about the krogans? Pretty sure they aren't with the turians or the salarians (considering the timeline). So that would leave either the asari ou human Ark.

Yeah, agreed. They would definitely not be with the other two.

No Quarians?

If there's going to be quarians in the game, I wouldn't mind having a couple like Xen and Kal'Reegar

BioWare employs fire ecology: watches internet burn, encourages new growth in Andromeda. I like it.
