There’s a Tom Scott video where he illustrates the difference between a million USD and a billion USD, expressed as the size of a stack of 1 dollar bills.
A million was about the size of a football field and a less than two minute walk.
A billion took him from somewhere near London all the way to the east coast, and had him drive for over an hour.
I have a group of friends with whom I play werewolves occasionally. I volunteered to be the forever GM, since I find that I have more fun in the game if I’m the one running it than if I’m in the middle of it.
