I still don't know what 'fnv' is exactly. It could be a new thing that I haven't heard of. Maybe you can start by saying if it's a brand, a fictional entity or something else.
I'm not entirely sure without more context. 'Dead money' could refer to money that's tied up and not being productively used. Maybe 'the whole sad story' is about how that money got into such a state. It could be related to a financial loss, perhaps in an investment or a business deal.
The Dead Money New Vegas story mainly focuses on the Courier being trapped in the Sierra Madre. It's a place that was once a grand casino but now is a deadly zone. The story has elements of survival as the Courier has to deal with the various threats there, such as the ghost people. It also involves a complex plot of finding treasures while trying to escape the Sierra Madre's clutches.
The sad story of 'dead money' could involve someone losing a significant amount of money through fraud or poor financial decisions, leading to stress and financial instability. Or it could be about a business that has tied up capital in unproductive assets.
I'm not sure specifically which 'fnv' you are referring to. There could be many things named fnv. It might be a project, a character in a specific game or story that I'm not familiar with. Without more context, it's hard to tell the whole sad story.
One of the best companion stories in FNV is probably Boone's. His backstory of being a former NCR sniper and his quest related to his wife's death is really engaging. It adds depth to his character and the overall lore of the game.
One of the best ways is to hunt. You can hunt animals like deer, elk, and bison. Their pelts and parts can be sold at trappers or general stores for a good amount of money. Also, fishing can be profitable. Catch big fish and sell them at the right places.
The Courier is the central character in the Dead Money New Vegas story. Father Elijah is a very important character. He's sort of the mastermind behind many of the events in the Sierra Madre. There are also the companions like Dog/God. Dog is more of the friendly, helpful side, while God is the more aggressive and unpredictable part of that entity. They add an interesting dynamic to the story.
Well, it might imply a story where money is involved and the outcome is completely sad and perhaps even disastrous. Maybe someone lost a lot of money in a really bad way or there was some kind of financial tragedy.
