Soooo…. I have a new favourite setting to base Sci-Fi stories. It’s called Proxima Centauri B. What’s really exciting is that it is a real planet. Scientists are interested in this planet because up to now it is the closest planet that might be able to support life. And it has some great fodder that lends itself to interesting games and stories.
Such as it revolves around a red star. It is tidally locked, which means the same side always faces the sun and the other side has never seen it. So one side is unbelievably cold and the other hot.
If mankind would settle on it we would have to live on the horizon to avoid burning to a crisp or freezing like a popsicle. Here where hot meets cold theoretically there will be constant hurricanes.
Therefore mankind would have to live in walled cities situated in massive canyons that have likely formed, and from there dig down.
So people would live and move around the planet in this straight line, except for the most desperate military manuvours.
In my opinion, it makes for great story telling and game mechanics
