All great questions man. I have one or two to add if they arent already asked and i missed them:
Re: Remnant.
So Peebee creates the name Remnant for convenience...just so we have something to call them, but the reason she calls them Remnant is because she describes how evidence leads towards all of this type of tech on every world that was left by this precursor race are ALL "remnants" of something bigger. Or tools left behind by something bigger. So that instantly leads me to ask....
Who built this technology that is spread across the entire cluster or universe as we know it?
Why have they left these worlds after installing these epic terraforming and atmospheric-manipulation devices?
Are they coming back?
Will they be pissed at us for interfering with their stuff?
Mainly I just want to know who they are. Clearly they are a super advanced race to be able to build this stuff, and transport it galaxy-wide, and install it deep beneath planets surfaces. And they seem to predate every other race and species. So maybe they are extinct? To me it seems a bit like the mystery of the Pyramids but we are talking about Pyramids that were built before Humans were around 🙂 All we get to see are their automated robotics that tend to guard Remnant areas and sites. The observers etc
NOTE - I am only 55% through so if this is something that gets revealed later on through the story mode please dont spoil it for me by telling me the answer...Thanks 🙂
ALSO - I havent played previous Mass Effect games yet (I will be soon tho) so same goes - if its something that gets revealed in story dont tell me 🙂
