So I haven't actually gotten to the point where I travel to the Mojave yet, but while reading the forums someone brought up the point that you leave the CW for 9 years, but everything is the same. So I want to start brainstorming ideas for what changes could have taken place.
Oasis- if the courier decided to not kill the trees heart, spread more greenery near the oasis.
NPCs- some changes to NPCs, children growing up, old people dying.
Respawn- after 9 years the ruins have been moved back into. Could have new bosses.
- Growth- depending on how things are when you hop the train, towns could be larger.
Any other ideas?
