Think of it this way: it's trivially easy to randomly generate terrain for a video game world. The "size" of the in-game universe is just an arbitrary parameter.

Populating the world with interesting NPCs, is, however, a vastly more difficult problem than just scaling the same copy-pasted planets and stars across light years.

So no, the size of our universe is just a scale parameter. There's no evidence that it's more computationally complex out there than here, and computational complexity is the only interesting metric.

This assumes humans are interesting NPCs. I feel like we're the bizarre comic relief planet for the really interesting players to have the space adventure of the day.

I understand your point, though, but even if it was true, keeping track of all the physics in the Universe's filler would demand more processing power than what is needed for our planet. The speed of light would be our rendering depth, and that's still an unthinkable amount of computing, copy-paste included.
