Indeed, there's even a secret project at Obsidian, one unlikely to be Fallout: New Vegas 2, but whatever comes of it, there will always be fans singing the original New Vegas' praises. With games like The Outer Worlds, Grounded, and the upcoming Avowed, Obsidian has proven that its acquisition by Microsoft may eventually elevate both companies in the coming years. Instead, it could be a culmination of Obsidian's powerhouse-like development achievements. Of course, there's a lot of variables and it's unlikely that Fallout: New Vegas 2 would play exactly like The Outer Worlds.
For example, The Outer Worlds companions could permanently die (which only happens on hardcore in New Vegas), meaning players had to really consider if they wanted to reload to save Felix. In Dead Money, players must work alongside three other captured wastelanders to recover the Sierra Madre Casino treasure. It wasn't a full leap into a companion-influenced story, but it was close enough that players would often have to react. Each character played a unique role in the overarching story, often adding their own thoughts to the world around them. Characters like Parvati were a perfect fit within The Outer Worlds, while others like SAM brought the imagination ever forward.
