Andromeda Initiative briefings (6/6 Golden Worlds and Settlements)

And you somehow think that the fleet guarding wouldn't be able to destroy the Collector ship that a single Normandy would send to oblivion later on? That's really, really quite the reach. Collectors ain't Reapers, just so you know. That plot armor of yours is basically something to try and legitimatize your complaint, but it won't work. Nothing about the clash between the two is implausible. You just need to accept the fact that the Collector ship isn't that strong and was easily moved with defense systems in Horizon. There's also that.

Could you tell me its purpose? I may have misread it.

I'm beginning to wonder if you even played Mass Effect or read the codex.

All Sovereign had to do was kill the planners. Indoctrinated agents or geth would suffice. Or collectors or their agents. All of these were employed throughout all the Mass Effect story.

The Normandy was an example of the most advanced technology available. It could not make a 600 year trip to another galaxy due to many technological limitations - most which have already been mentioned in this thread and are also in the Mass Effect codex. Read them.

The Citadel and the Mass Relays were advanced technology we didn't understand and could not replicate. Even the Protheans had difficulty doing so, they only managed a small-scale prototype of a mass relay. The Reapers devised this technological mouse trap so that when civilizations started to approach understanding this technology - they would be wiped out roughly every 50000 years. Any attempt to escape this mouse trap - the Nexus - would have been stomped. 

Cerberus was anti-alien long before any indoctrination. That was their whole shtick... did you not pay attention to them being described in ME1? Or the conversation you could have with Miranda about them being anti-alien? They only approached cooperation with aliens when faced with the Reaper threat. 

Geth. Right, they were so capable since forever. That's why they didn't dare to attack The Citadel or anything else of that escape before they had a huge ass Reaper in the front.

Um... The Nexus is a ship, a big one. Its purpose being similar to the Citadel, but not being an exact copy of the Citadel. The tech behind can be perfectly reachable. It's not like they chopped one of the Citadel's arm and began building from there.

The Geth didn't attack the Citadel before Sovereign arrived because they had no desire to them. Instead they wanted to remain in isolation and work on how to become one. Sovereign approached them, most disagreed with Sovereign but around 5% did and those became the Heretics who we fight in ME1 and ME2. 

The issue with the Nexus I have is not so much the technology but more the fact they built something that massive in less than a decade. That is not possible even in the time of Mass Effect. 

Canis Major  and several other dwarf galaxies from the Local Group are satellites of the Milky Way.

Not to mention... why would they even bother?  If i were the Reapers... and extension the collectors.. i would be quite gleeful the stupid humans were wasting resources on this nonsense instead of preparing for war with us.  And plus either attacking Sol with the Collectors or Soverign would likely alert the galaxy to the threat we pose.

Prior to its discover in 2003, it was the Sagittarius Dwarf Elliptical Galaxy that held the position of closest galaxy to our own. At 75,000 light years away. This dwarf galaxy, which consists of four globular clusters that measure some 10,000 light-years in diameter, was discovered in 1994. Prior to that, the Large Magellanic Cloud was thought to be our closest neighbor.

There is absolutely no rational reason to travel to Andromeda when there are closer galaxies. They probably used it because they liked the name and it's spiral resemblance to our Milky Way. 

Where were Sovereign indoctrinated agents in ME1? Saren, Benezia and...? You talk as if a single person can actually do something, and as if that someone is easily reachable. Don't say I'm the one who didn't play the games here. Where's that mass indoctrination factory in the lore of ME1?

Geth. Right, they were so capable since forever. That's why they didn't dare to attack The Citadel or anything else of that escape before they had a huge ass Reaper in the front.

Um... The Nexus is a ship, a big one. Its purpose being similar to the Citadel, but not being an exact copy of the Citadel. The tech behind can be perfectly reachable. It's not like they chopped one of the Citadel's arm and began building from there.

Cerberus was anti alien, yes, but they aren't anti human. I think you would know that. Sabotaging the Nexus or Ark would mean losses to all sides, not only Aliens, also stopping this tremendous feat we would accomplish. There's no reason for that to happen. Last time I checked, they saved thr Council as well. There you go your super anti alien nonsense.

And yeah a the Collector ship attacking any target in Sol would have been suicide, for them.

Not one did the Reapers state their objectives as 'containment'

No, their purpose was to prevent advanced life evolving to a point they could create synthetic life that will wipe out all life. We are near that cusp hence them harvesting us. So letting enough of us go to repopulate and continue to advance is against their goals thus stopping us is only logical.
