What was the Japanese reception to Nier crossover?

[Mansion]

The first is a place that people can travel to, and the aliens just traveled there.
Nothing is drawing aliens to the source, that's just where we were up until Shadow Bringers so that's where SQEX wrote storylines. If the Omega raids were happening in Shadow Bringers they probably would have taken place on The First instead.

I can accept a lot of what is going on with the Nier raid but that's my main gripe. Sure, I get the "the expansion is on the First so the raid must be", but that's not an in game explanation.
Midgar and Omega landed on the Source after the Sundering, through space travel. So my understanding was that in the physical plane, The Source would be accessible physically through travelling. And Shards are just other dimensions which you can travel to through more complex means (Ascian magics for instance). But anything coming from outer space would see the Source, and land on the Source.

But now, we have the Nier aliens that came directly on the First (I don't recall any mention that they came to the Source before "phasing" into the First). So did Hydealyn's Sundering applied further from the original planet, and the Nier aliens only exist in that dimension? (which would technically mean that this is the "same" dimension as our real world, or at least Drakengard/Nier's depiction of it.) Or is there something I am missing?

The Yorha enemies didn't come to the First through space travel, so any limitation of going to the shard via space travel wouldn't apply.

I don't believe it has ever been clarified how far the sundering spread, it's generally assumed that it was a rather localized event but no one is really sure. I don't think the writers even know, leaving it deliberately open ended just in case they fancy doing something with it later.

That aside though, I got the impression the whole Nier raid arrived (and left) through a dimension hopping portal. I don't see any real reason they would have had to end up on the Source.
