This is half question and half suggestion thing. I think Fallout 4 would be a great game for Vedal and one (or both) of the twins to play together. Since Neuro is able to be integrated into Outer Wild ship and can also play Minecraft: Is it possible to implement Neuro or integrate her into one of the Fallout 4 NPC companion, while Vedal play as the vault dweller?
I don't know anything about programming and I don't even know if it's feasible, but the idea that Neuro or Evil controlling one of the companion in Fallout 4 while letting them choose major choices in the game sounds like a fun watch.
Furthermore the game touches heavily on topic of A.I and android, and the moral question/choices that comes with it. I would be very interested to see what choices Neuro or Evil will make in Fallout 4 world.
