The SAM matter and what it entails.

Yeah this is Mac Walters again all right, didnt expect the story to pan out any greater.

But its been like this since the ME2 tbh. I mean there Shepard died, he crashed into the planet and burned in the atmosphere and then they managed to bring him back...? And the man never questions this, never ponders it, never makes more effort to go deeper what cerberus might have done to him(just trust Miranda and TIM yes), he just merrily accepts it all as "i got better" "ok lets help cerberus". The series has been downhill from there lore wise, cause they just keep handwaving things away when its convenient.

2) ANDROMEDA ISSUES.

Gameplay wise, I must admit I find zero sense in the resources SAM adds to the table for Ryder. For starters, where does it came from the eezo you use when switching from a tech loadout to a biotic one?
Duh?
Is Ryder a latent biotic? Habitat 7 atmosphere screwed us over when we breathed its air? Just think about it a moment…
And while I understand (but don’t condone) the limitation to only 3 powers at a time, I really don’t understand why SAM has been needed to justify the ability of the player to learn multi-disciplinary abilities. Forcing such a mechanic AND using SAM to justify it, seems silly and overcomplicating. Mmhh… more like over overcomplicating it: like solving a problem that wasn’t even there applying quantum physics to create it…
You BECOME the pathfinder: it is in the job description to learn different abilities to complete your job. Should I believe among the 100’000 colonists we brought with us, no one was willingly to earn some credits to teach our Ryder how to best push, throw or simply mod our omnitool to incinerate things?
You want to plug Ryder to an AI because it’s a core element of the plot? Please do: I’m very curious to know what is the aim and the need, but forcing SAM to be plugged just to fight (again, something in the Pathfinder’s very job description) seems shallow and empty as reasons go.
And more: while Alec was an idealist (how much misguided is moot here) and built a wonder of an AI, he plugged SAM to himself out of free will, knowing full well the dangers of such an action. And I’m even cool with it…
But after:
a) daddy dearest passes away
we discover that he got beyond the backs of everyone, reshaping human condition on the road to organic and synthetic reunification
c) he created an AI able to interface with organics brains (this is the kind of shit that changes the course of history forever people!).
d) that very AI is now directly plugged to our brain
e) the AI itself can’t explain everything to us because Alec himself kept files locked away from us
f) our brother/sister is in a coma
g) we must save the day, outnumbered, outgunned and in uncharted territory.

The reaction of our character to all of the above can’t simply be “It’s cool, let’s go adventuring.”
WHAT?
The other characters too should have at least SOME reserves about all of this: T’Perro though? “Thanks for sharing this with me, Ryder, but we’re cool. Just keep an eye on Drack please.”
If you really want Andromeda to possess a lighter tone than ME:A, you MUST balance those elements with the direction of the story and justify them in a believable way. I can’t stay silent about this, sorry: for me, it is terrible writing if a character is subjected to all of the above with zero mental consequences.
Can we sympathize fully with a character that has no character? Who is unable to relate with the plot elements he is the protagonist of? Of course, not!
And it’s terrible when that same character is the main hero of the story…
From what I’ve seen until now, the premises for ME:A are at best a confused mish-mash of word shattering, important revelations who are immediately devaluated for no good reasons. Wouldn’t have been better to stay silent about them at all? To try something else? Putting something in a plot because “rule of cool” is the poorest kind of act I can think of to begin a new story: it doesn’t work, it is nonsensical and it leaves the worst kind of impression.

I really hope the rest of the game will solve and address all of this, but I have to admit the premises are not good for now… and we’re one week before launch.

Ryder didn't really have much of a choice. It seems he'd die if they try to separate the two.
Also, he doesn't go exploring for fun. He's trying to follow his father's footsteps in helping humanity finding a home in Andromeda. I don't like how the passage of power goes as well as the responses to Alec's death, but he's not leaving the twin for fun.

As I said, I agree about the problem with dealing with the tragedies. Although Sara had a more emotional option.
I didn't address SAM's problems because I want to see them for myself. One thing is clear, they decided to follow in the footsteps of the 'humanity is special and awesome' troupe that enveloped the trilogy (from the start).
Is it possible Alec was helped by some quarians about developing SAM?

they do, but Tali's father researched on them to find a means to control/destroy them, as Xen. There might be some quarians that he found to help him.

You, um, haven't been looking very hard. Hell, expressing concern over your sibling's medical status is one of the first things Ryder can do in the game. In both the trial and in gameplay released since on YouTube, there are ample opportunities to communicate personal distress over your family's situation (or not, if that's your thing).

The AI launch between ME2 and ME3.
How is that relevant? AI can still be created. One was created by random people and we found it on the citadel in ME. The problem with SAM is how advanced he is, and quarian help might justify partially. Although I think the explanation will at least be influenced by 'humans are awesome and can do everything'.

Ok, let me rephrase that:
Expressing concern in any relatable way. There is a difference between a stoic conduct and being emotionless. And by the time we earn the Tempest, the exploring leitmotiv has been forced down our gullet and everyone is ok with it. Problems? What problems?
Oh, you mean the Nexus uprising? A little thing, a minor thing: we had a splinter group who needed to be put down by the Krogan. Then they left and we kicked out the Krogan for good measure.
See? No problem: paranoia, panic and fear running rampant on the Nexus?
Nope, no problem at all. Well, you know, some vocal elements of the crew. But nothing worthy of interest, really. Just like your father’s death.
Now take your ship and go drill some holes in the sand of Eos…  I've heard of 30 meters tall robots who fart candies down there.

Not really impressed here.
Seriously, they wanted Andromeda to be happier? Lighter? Then why the hell bothering with adding such elements to the plot?

And anyway, this thread has more to do the problem tied to the existence of SAM and how they have not been addressed or even considered.

It is explained in the briefing videos regarding SAM and the pathfinder team: it is stated that it can create thoughts like they were your own.
And ok, let's admit Alec managed to work on the SAMs for decades: still, where the resources, technology, technological know-how, funds and permission came from for all of this?
The Alliance didn't back his research: Alec was toxic to them. The Council? They are even more cowardly than the Alliance in regards to AIs research: and an AI able to plug to organic brains and generate fake memories?
The Turian councillor would have declared Exterminatus at the mere idea of it.
