I choose to evacuate Zion and when I travel back there's no humans there - apart from a few white legs... Which makes sense but I was hoping at least Dead Horses tribals left...

What I really want to know is: If you chose to crush the white legs will the dead horses and sorrows be there when you travel back?

Yes.

Thanks buddy. I totally rushed it the end. Picked a terrible ending. I'll need to reload an earlier save...

why does it matter if theyre not there?

It doesn't ACTUALLY matter. I'd just prefer if they were there.

so they dont really do anything for ya, it just feels empty?

Lets say the strip and all the towns were devoid of any person who wasn't a shop owner or directly involved wiht the quest?
Same princible here.

Except there's still no shop owners or Quests left either....just a few Dead Horses creeping around..

So wait...

If you evacuate, the Sorrows AND the Dead Horses leave the area?

What part of "Evacuate all the Sorrows so they can leave Zion forever" and "Dead Horses are only around to protect Sorrows so they return home" didn't you understand. Another reason why Graham's way is the best.

Ah ok, I didn't catch the latter part in the dialog.

If you evacuate zion, do the white legs still remain there?

I really like killing them...
