Greetings!
In my own campaign world, I have a culture of Dwarves that have embraced a Greek-like culture of sophisticated city-states, extensive coin-based economies, high culture, and long-distance trade, by both land and sea. At first glance, it can seem like, "Well, that is just another Greek-based culture, so what is the point?" However, having Dwarves embrace such a culture and motifs inherently brings something different to the table, as it were. After all, while there was historically a dominant Hellenistic culture, there were also some crazy cultural blends going on that gave rise to some interesting kingdoms and realms--such as in North Africa, along the Tunisian and Libyan coasts; in Central Asia, where you had a fusion of nomadic steppe culture, eastern, Persian culture, blended with Greek culture; then of course, there were also kingdoms that were a hybrid of Greek, Indian, and Central Asian cultures as well. All such hybrid cultures had much in common with the parent Greek culture, and yet were also quite distinctive and different.
It is in such a spirit that I developed my own hybrid Dwarf and Greek-like culture. It is definitely something quite different for Dwarf player characters, or NPC's.
Semper Fidelis,
