NovaRain,
I'm pretty sure I have got the best ending for Broken Hills, in my last playthrough.
(All quests for Marcus were completed, the air purifier repaired, uranium ore refined and the mutant haters Jacob and Eileen imprisoned.)
.. I still can't get the best ending ..
Just for sure: what "best" ending do you expect?
There are three possible endings for the Broken Hills, but alas, all of them are despairing:
[spoiler:13877a149b]A:
1:The destruction of the mutants ensured the death of the town.
2:Without their strength and ability to withstand the toxins within the mine, the valuable ore proved unattainable.
3:Those who caused this destruction rejoiced at first… until they realized the foolishness of what they had done.
4:They struggled to keep the community flourishing, but to no avail.
5:The winds and the waste scoured Broken Hills from the map.
B:
1:With the destruction of the conspiracy to destroy the mutants, Broken Hills began to thrive.
2:Then the uranium ran out.
3:The city, having lost its sole reason for existing, slowly dispersed.
4:The residents carried their riches with them, leaving the place a wind-swept, desolate ghost town.
5:A few hold-outs remained, attempting to eke out a pathetic existence, but eventually, they too, disappeared.
C:
1:Shortly after your last departure, the powder keg of racial tension in Broken Hills exploded.
2:Racist humans fought against mutants, ghouls, and humans who had sided with the mutants.
3:The few survivors of the battle destroyed the mine, ensuring no one else could profit by it, and disappeared into the wastes.
Note, that the line 2 in the C variant is modified by the RP. That seems to be an one and only change, compare to the vanilla game:
2:Racist humans fought against mutants, ghouls, and humans who sided with the mutants.

I think, the variant "B" is the best possible; and that's what I was got. Damn, even the poor treasure hunter was forgotten in the dark, for an eternity!
