A common plot point is the struggle for medical resources. In the post - apocalyptic world of 'Fallout New Vegas', finding proper medical care for a pregnant woman is extremely difficult. So, the character may have to embark on a dangerous journey to find a doctor or medical supplies.
Another interesting plot point could be the reaction of the community. If a character is pregnant, how do the other survivors in the wasteland react? Some might be helpful and protective, while others might see it as a burden or a weakness. This can lead to various social and moral dilemmas within the story.
The fear of the unknown is also a big plot point. The pregnant character may be worried about the kind of world her child will be born into. Will it be a world full of radiation, mutants, and violence? How can she protect her child from these threats? This internal conflict can drive the story forward and add depth to the character.
A plot could involve a group of settlers from Fallout 3 trying to make a new start in the Mojave. They run into trouble with the various factions in New Vegas. Meanwhile, a character from New Vegas goes to the Capital Wasteland to learn about their different ways of survival. This leads to an exchange of ideas and technology between the two groups, as well as some clashes due to different values.
One plot idea could be a team of RWBY characters getting teleported into the Fallout New Vegas wasteland. They'd have to adapt to the harsh environment, deal with radiation, and face off against the various factions in the game. Another could be a character from Fallout New Vegas traveling to the RWBY world and learning about the concept of Dust and Huntsmen.
A more complex plot might be that there is a dimensional rift that is causing chaos in both universes. Characters from both Fallout New Vegas and RWBY have to work together to close the rift. In the process, they learn about each other's worlds, values, and fighting styles. The contrast between the post - apocalyptic technology and magic - based abilities in RWBY could lead to some really interesting interactions and story developments.
One main plot point is Ulysses' summons. He wants the Courier to come to the Divide. Another is the exploration of the Divide itself, which is filled with danger. Also, the Courier's discovery of their connection to the past events in the Divide is a crucial plot point.
Another is the search for valuable resources. In the post - apocalyptic world, things like water, ammo, and pre - war technology are highly sought after. Players' characters are often on a quest to find these resources for themselves or for the faction they side with. Also, there are often plot points related to uncovering secrets of the old world. Maybe finding out what really happened to cause the apocalypse in the first place or locating a hidden vault with advanced technology.
One interesting story is about the Courier's journey to find out who shot them. It's a quest for revenge and truth that leads through many dangerous areas and encounters with various factions in the Mojave Wasteland.
There are fanfictions that focus on the relationships between the different factions in the game. A story could be about a character trying to broker peace between the NCR and the Legion. This would involve a lot of political intrigue and difficult decisions as the character has to deal with the different ideologies of each faction.
One idea could be creating an OC who is a former NCR soldier turned bounty hunter. They could have a complex backstory of disillusionment with the NCR's politics and find a new purpose in tracking down dangerous criminals in the Mojave Wasteland.
One idea could be exploring the backstory of a minor character in the game, like a random caravan trader. You could create a whole story about how they got into the caravan business, their adventures on the roads, and the dangerous encounters they've had. Another plot could revolve around a new faction emerging in the Mojave Wasteland, and how it affects the existing power balance among the NCR, Legion, and Mr. House. Maybe this new faction has a unique ideology or technology that shakes things up.
A plot idea could be that the Courier discovers a powerful relic in the Fallout world that has the power to connect different universes. This relic accidentally transports the Courier and some of the key RWBY characters to a strange in - between realm. In this realm, they have to work together to find a way back to their respective worlds while also facing challenges that are a mix of both Fallout and RWBY elements, like Grimm - like creatures with post - apocalyptic mutations and bandits with Dust - powered weapons.
