Bioware story hole how that Massive Nexus station reach Andromeda? (not spoiler)

Anyone care to translate the above?

The Nexus is meant to be a station but it's a starship.

It's also only got room for 200,000 people.

Not like the Citadel.

Sweatshop labor + geonosians = profit. 

The Nexus is powered by plot necessity. Best engine there is.

The Nexus is supposed to be a massive star ship. That said, it is lore breaking. The entire expedition shouldn't have been possible at the time it was supposed to have set off. The technology required didn't exist going off the lore from trilogy. There are a couple of threads about problems with MEA you can read through for more in depth discussion.

Why didn't everyone travel in the nexus then?

What does Quarian sweat taste like again?

Or why wasn't there any pathfinders on the Nexus when it left the Milky Way and not just the one's on the ships?

Aaand...the next thing you're going to ask is 'how da hell Citadel got to Anderson's Birthplace London?', right?..

That was only the crew in stasis, the max population is 1.2 mil (2.7 mil when the station is complete).

...and yes, it is missing engines, but since we never saw it actually arrive, maybe the engines got torn down already and used for building... or they used boosters they dropped off at some point? Dunno. The whole plan is so stupid on numerous levels, this detail is not really that important.

I might have 10 years ago... today, not so much.

I'm not saying the effort in itself is stupid - especially considering what we learn later in the game, just that the plan has SO many problems...
