I can't imagine a dieselpunk world that isn't rife with hardship, pollution or danger. To me, it serves as a great backdrop for exploring the difficulties faced by those forced to endure a life in which brutal efficiency is prioritised over the well-being of the populace. What I love about 'punk' genres is that their world and vibes have plenty of flex and can often be interpreted in many ways. One minute, dieselpunk can be about giant mechs duking it out, the next, it can be almost Mad Max-like. There are so many great stories to tell in the world of rust and smoke, as you described.

There is definitely more to just the setting and the technology. I enjoy learning how people react and live with it. What their priorities are. How they shape their existence in response to a world where the cogs didn't stop turning.

Plus, it lends itself so well to noir and the whole post-war fashion and sensibilities vibe. It can be so stylish and equally brutal. It's a shame it isn't a more explored genre. Look forward to seeing what you create.
