If someone already responded to you, then sorry for this post, I haven't read the whole thread; I think the whole thing about the Citadel was that it was the only means for the Reapers to quickly access our galaxy from dark space. When the ability for them to use it was cut off in Mass Effect, the reapers had to physically enter our galaxy by way of non instantaneous travel. (Which we see at the end of Mass Effect 2) Because they don't have the convenience of using the Citadel, they have to instead reach a Mass Relay in order to spread through the Galaxy. Had they been able to use the Citadel, they would have arrived already and presumably killed off everyone.poiumty said:And then there's Mass Effect. All that shit about the Citadel being the only entry to the galaxy from deep space?
So it really isn't just a convenient plot portal, it's simple logic: can't take the short cut, so you take the long way.
I don't really understand your point here, Mass Relays exist to connect the galaxy - an easy way of getting from point A to point B, or point F, R, X etc...poiumty said:Nah dawg, here's the convenient plot portal and access to ALL OF THE RELAYS. ALL OF THEM.
I'll put the rest in spoilers for those who haven't played the Arrival DLC.
In the arrival, you're at the far edge of the galaxy; the whole point of the DLC is to hammer out the fact that even though you've stopped the Reapers from invading via the Citadel, they are still determined to reach our Galaxy - it's just taken them a few years. If you can disrupt their ability to use the closest Mass Relay available to them, then it will take them even longer to spread through the galaxy.
Everything thus far has been about disrupting/delaying the Reapers. That's all you can really do when you don't have a solid means by which to destroy the threat presented to you.
