>>95870696I was back at the drawing board (literally) and started considering this.
The general gameplay takes place in a stubborn old republic with rugged highlands, lots of cattle ranching, and a few big cities, especially the capitol. Not unlike a weird mashup of Tuscany, Liguria, and Texas.
Now, because Republics *tend* to be places of innovation, I was going to make them on the cutting edge, but in reality most of the civilization lives a feudal life out in the hills and pastures - answering to Barons and Viscounts ruling on behalf of the core City State that is the heart of the Republic. Really the only industry and 'advanced' society to speak of is going to be along one of two rivers, including the only good sea port.
So, rather than the cutting edge, maybe they're gruff (almost dwarfcore) traditionalists who have a lot of great innovations under their belt (when it comes to glasswork, textiles, and even some rudimentary automation) but is way behind the 8 ball on other things. Not unlike the Ottomans or Persians in the gunpowder age where they pioneered several things then fell behind.
In this example I think I have a perfect counterpart to Prussia to be starting to ramp up military science to that scary degree where musketeers become the spine of the army rather than just one arm.
That way the players and their sandbox can have this looming Gustavus Adolphus / Frederick the Great figure in the distance threatening the status quo.
