Today's prompt was 'muffin', as in boo-berry...

Create situations, not plots. A game isn't a TV show or movie, as I often make the mistake. A game session is a bunch of situations which are offered for the players and it is up to them what they choose for their PCs to do. We play to find out what happens, we don't follow a script down a railroad!

That being said, there's something about an interstellar or galactic railroad. I was reading about a concept called the interstellar compact where star-going habitats, not star ships, cycle around along circular routes between stars and brown dwarfs, turning slowly against the galactic magnetic field and presumably slowing over time, then being accelerated again every time they pass by a system. People and cargo (or corpse-icicles as cargo!) are accelerated up to or down from speed. Presumably you need a ticket!
