I've done limited research on what the devs plan to add, so apologies if I'm restating anything they have already brought up. I think human civilization should play a bit more of a role in vintage story, especially in things like trade routes and caravans. The main story village should still remain the closest, however, it would be interesting to see other villages. Maybe as the game story continues villagers could even start commenting on how they have heard about your exploits in the world. Another thing I think would be interesting is to highlight how villages are still not fairing the best, maybe after heavy temporal storms the streets of a village are a bit more empty, or in extreme cases entire villages are temporarly wiped out for a couple seasons until new villagers move in. (the main story related village should obviously be exempt from this, maybe explained by the cautious way they chose to survive in-game) This could lead to moments where you have to help protect a valuable trading ally or risk losing them for a year. This ties into the uses of caravans; maybe they could stop by your base and offer a limited set of goods, or even ask for shelter when temporal storms are imminent. You could also possibly be able to travel with them as a more expensive form of fast travel; I'm not the biggest fan of this though. Finally, ruins could tie into villages as well. Finding a destroyed village or remnants of a caravan would be excellent world-building and lend itself to the daily tragedies that are dealt with by those who are still alive.
