No, because Vigil tells us a different story. The Reapers conquer the Citadel first, shut off the mass relays which makes sure all main communications and transportations are completely cut, thus ensuring that each star system is isolated and cut off from others. World by world, system by system, every planet would then be taken over. The Reapers also relied on their indoctrinated population as an extra army to aid in their invasions.
If their numbers “darken the sky of every world” then they wouldn't be doing this. It took the Reapers centuries to defeat and conquer the Protheans. Obviously, what Sovereign is saying is not true. Either it’s trash talking like Harbinger or it perhaps meant something different when saying that line.
That said, the Reapers didn't have that luxury with the current cycle, and they still were able to simultaneously assault dozens of planetary systems (including the homeworlds) of several species and overwhelm without too much trouble. The Turians, though putting up a strong defense, knew their world was doomed. It was an attrition war and the Reapers had them outgunned and outnumbered. While Sovereign's statement of 'we will darken the sky of every world with our numbers' was likely hyperbole, they still had the capability to take on all the major races of the galaxy on their own on dozens of worlds and still be hilariously curbstomping them. I think the Reapers, as machines, were more pliable to efficiency. They could take their time and be as thorough as they required. As well, to an extent, what Javik says contradicts (and possibly retcons) what Vigil says in ME1 (yet another establishment of BW disregarding established lore for their own writing purposes while invalidating the entire plot of ME1, but whatever). Javik implies that he once led his own team in a ship across the galaxy to fight the Reapers, and the Protheans had the Crucible built (which would require a lot more resources than what any isolated system cut off from all the others in both travel and communications could achieve). As well, I'd imagine that the Protheans had some kind of protocol or action that was designed to buy as much time as possible from the Reapers. Imagine the Cole Protocol from Halo, a directive established by the humans to prevent the Covenant from finding Earth or any other human colonies.
In practice, it was intended to prevent Covenant's retrieval of data that contained the location of Earth; it forbade retreating vessels from setting a direct slipspace course toward any human population center, as the Covenant were able to track slipspace travel vectors and calculate the evacuating ship's destination. The policy also stated that to prevent capture, any military or civilian vessel, in the event of an emergency evacuation, was to self-destruct, after wiping all data matrices, to prevent the advance of the Covenant.
The Cole Protocol Article 1 To safeguard and protect the Inner Colonies and Earth, all UNSC vessels or stations must not be captured with intact navigation databases that may lead Covenant forces to human civilian population centers. If any Covenant forces are detected: 1. Activate selective purge of databases on all ship-based and planetary data networks. 2. Initiate triple-screen check to ensure all data has been erased and all backups neutralized. 3. Execute viral data scavengers (Download from UNSCTTP://EPWW:COLEPROTOCOL/Virtualscav/fbr.091) 4. If retreating from Covenant forces, all ships must enter Slipstream space with randomized vectors NOT directed toward Earth, the Inner Colonies, or any other human population center.[note 1] 5. In case of imminent capture by Covenant forces and boarders, all UNSC ships MUST self-destruct. Violation of this directive will be considered an act of TREASON and pursuant to UNSC Military law articles JAG 845-P and JAG 7556-L, such violations are punishable by life imprisonment or execution.
It wouldn't be a stretch to imagine that, with the updated Prothean/Reaper war scenario provided by ME3 over the ME1 lore, the Protheans might have enacted some kind of directive similar to the CP (since it seems that BW also did away with the lore concerning the Reapers knowing the exact populations and locations of Prothean worlds).
On that note, I'm inclined to believe Sovereign meant something else with its speech.
No. Well, at least not in the way you’re implying.
Fans wanted an option to refuse and win. They didn’t get it.
Fans wanted a “Reapers win” scenario where the Reapers win as a result of the player’s failed accomplishments and because of making the wrong choices throughout the whole trilogy. They didn’t get this either.
True, but that's the way BW interpreted it (since the fans never specifically separated the two circumstances.
I disagree entirely with the idea behind a refusal victory. Not because I inherently disagree with the idea, but because in universe, you've already blown all your resources on the Crucible, and there's no way that the combined forces of what you have are going to take on an estimated 20,000 Reapers (the big ones) any of which dwarf the largest non-Reaper ship by leaps and bounds. It simply goes against the lore of the series and the Reapers to suddenly have the galactic fleets, all of whom were getting smacked around harder than a titan by a jaeger, find the power of heroism and win the day. Not saying it's you since you aren't advocating it, but that line of thinking is just so... David.
But yes, the second is definitely true; I am indeed for a bias in the games. I think anyone who played a full paragon or full renegade (or anyone who didn't play within certain bounds of characterization) deserved nothing but ultimate failure. That said, I know my opinion is a rather extremist one on that regard. Thus, I would say that you are correct though. We wanted to have the cumulative decisions count for victory or failure, and we ultimately didn't get that.
