It seems that there are very few persistent changes that can be made in the world. The NCR quest disappeared, but I get basically the same quest from Yes Man. Since I was on the strip, I decided to see what would happen if I killed Mr. For example, the Kings constantly send a dude to give me a stimpak or some caps whenever I'm in Freeside.īut here's an example of what I'm talking about: the NCR gave me a quest to go protect the President at Hoover Dam. I guess the Idolized/Liked/Accepted/Vilified statuses for the different groups make some difference. Now the casino is open again (which allowed me to use the chip glitch to get a few hundred thousand caps). The most persistent change I can see is when I got Primm a new sheriff. One NCR trooper did say 'I wish I could have been there to watch Caesar die.' That's it.

When I got to a high enough level, I fast-traveled to The Fort and killed every living creature inside, including Caesar himself. Nothing changes except that occasionally an NCR trooper says something like 'We've taken back Nelson!' What if some NPCs were to go set up a camp in those towns? What if one of those NPCs turned out to be a merchant who sells something very useful? I wiped out the Legion forces at Nipton and Nelson.
