I've put some things together and wanted to make it simple, but just now remembered and had the patience to actually come to the forum and post this. I see this is already at Mark III which is amazing how this is talked about. And thanks byne for keeping at it haha So I'll post here my "rant" about synthesis. Nothing new problably or maybe there is, but still, I'll express. Sorry about english, not my native language.
Oh, and it may have some novel stuff, [SPOILER ALERT]
Synthesis still bugging me. Could accept Destroy and Control because it makes sense in terms of what the plot worked with.
Going back to Mass Effect 2: Legion's loyalty mission provides two options: One to rewrite and another destroy. This would happen thanks to a massive magneic pulse that would reach the heretics and either rewrite them and destroy them. So, it's the type of pulse that actually exists at this time already even if it's just at a very small scale.
This pulse, or this type of tech the geth possess is very similar to what the crucible can do, but the Crucible have two differences:
- It affects the whole galaxy or at least a large scale.
- It can also contain a mix of matter stream, therefore it will not only send some kind of programming to override the Reapers or destroy their cores, but also bring actual matter with it.
The Destroy ending, in my opinion, it's the right ending however Mass Effect it's known for having little things considered cannon, aside from Udina that it's meant to be the political mind and not Anderson.
Simply makes sense. It's Shepard's objective since the very beginning, it's what everyone wants, and that's what people have been dying for.
The Control ending (hypothetically speaking) also makes sense, no matter if it's pure indoctrination or pure control. The electromagnetic pulse could rewrite the consensus of the Reapers the same way it was done with the geth, and since it's possible to make a matter stream, it would be also possible to destroy Shepard's matter while keeping his/her thoughts intact somewhere in the Crucible's/Citadel core programming.
Synthesis ending, that's where my head just blows up. Hypothetically makes sense since the pulse can stream matter, but still bothers me. First this would tell us that the original designers of the Crucible (but also Reaper victims) intended to merge themselves with synthetics. Maybe to have an edge over the Reapers in technological terms and warfight resilience. But still, how can this just pop-up in organics? So perfect. How can someone that just been merged with green synthetics and have glowing eyes act so normal, so ok with it? Like another day at the bach?
Plus, this is what buggers me most: even if the Crucible is meant for instantaneous effects, synthesis could also be possible if someone chooses the Control option. The Reapers are controled, their information is now in the possession of organics, so they could reach this evolutionary process in a matter of years thanks to the already existing technology and/or knowledge.
Not forgeting Shepard's objective is destoying the Reapers, and you would be very renegade if you'd choose otherwise. So, why would Destroying the Reapers be now at the ending, after all we've been though, a Renegade option? If I was a Reaper or was Indoctinated, this option would make perfect sense and I would feel my head was as clear as pure water. But after all we've been through, all the story we've seen, it's obvious this just isn't right. Something is out of place here.
If you read the novels, then you know who the Illusive Man is, his past, and also know that he had contact with Reaper devices (even if he didn't know what it was at the time). After the slightest contact, he started to "feel" the presence of other devices. Guess what, Saren did too and they both encountered each other and various situations, because Saren could also "feel" the presence of these devices that turned out to have the hability to turn turians into husks. Conscient but indoctrinated husks. These devices were destroyed from orbit with few people knowing about it, but this was enough motive for the Illusive Man to create Cereberus. Since the very begining of Cereberus, he studied indoctrination while Shepard was still playing with his first gun or his firs water gun (well...problably high school or military university) (well...he was simply ignorant enough) .He commited devious things, and sent reaper creatures that could "infect" other organics with a simple touch to Omega. The infected would eventually turn into reapers themselves with the same purpose: infection. It was kind of like a Zombie Reaper technology. These reaper forms were called adjutants and weren't on the game because of some tech problems I believe. These reapers were also responsible for the attack on Omega, creating a destraction
to make Aria flee. The reason it was attacked was because Kai Leng killed Aria's daughter, which turned into a big mess and alliance between her and the Illusive Man broke.
He was up to something with all that Collector crap, and I believe the Collectors where dispendable even if they served a very hostile, smart and indirect porpuse.
The Reapers could have been fooled many times, but one thing they did good was adapting. And so did the organics. So this was more of a psych war so it makes sense the last battle not being fough against a badass altered Illusive Man, but fought in a psychological level. There's motive for all the chat and messed up choices
and sequences to lead to the right path.
We have enough proof that while the Reapers were at sleep, the Illusive Man was the perfect puppet to weaken everything else and Shepard was the perfect match to counter attack.
If you're one to go deeper, then you can notice the main themes of ME are free will and the "wheel of life". But I won't go there. I find it unecessary and I think it could be a little more simple. But I'll let you think nonetheless.
Also, before Saren being Indoctrinated, the Alliance was studying an anctient artifact by a scientist that became indoctrinated, calling the artifact's presence in his head Sovereing. Thanks to the Alliance discovery, the Reapers decided that these humans were worthy of attention so humanity is the epicenter of everything and can be blamed for indoctrinating Saren. But we know enough that Saren always had this special lust for things that were new: or did he? Was a perfect puppet like IM maybe. This went a bit out of the theme, was brainstorming, but I also want to tell with this that there are key facts that should or could be included in the game for a better understanding of everyones story and capabilities, and not just mentioned vaguely in the games.
So, I still think both Control and Synthesis aren't quite right in the head, but Control is more right than Synthesis no doubt. I'm pretty sure there is Indoctrination at some point and ends at some point, and comes back at some point and so on, otherwise this is just a plain mess. I'm just enjoying MP now and a female Shepard

so I moved on with this, but like everyone here I actually enjoy thinking about this =p plus, the narrative of ME to me is like reading a book.
Cheers!
