Galaxies are closer together relative to their size than stars; but they’re still a few orders of magnitude farther apart than this.
The scale I’ve seen is: If the sun were the size of a ping pong ball, the next nearest star would be hundreds of miles away. But if the Milky Way were the size of a CD, Andromeda would be on the other side of the room.






Yep, this is the post I was looking for.
Writing a book means planning out plot and character arcs and going back to edit and such. Solo RPGs are an entirely different beast. They can inspire books, but they are not an authorial exercise.
