One often-overlooked detail in homebrew setting design is the way that social structures work. Usually, we pay attention to the details that make a setting distinct from the reality we know and don't pay much attention to the things that we take for granted--basic ideas about how people interact with each other and themselves. But these are some of the key building blocks of how our worlds function; without a solid grasp on the ways that people fit together in the homebrew setting, we lack a complete understanding of how individuals and society coexist (or come into conflict). One of my favorite aspects of worldbuilding is this kind of social mechanic.
In recent posts, I've devoted time and space to details like these: things like romantic and sexual relationships, parenting styles, and funeral rites. In an upcoming post, I'll be tackling friendships as well. Details like these may seem small, but each of them reveals more than we might realize right away. Relationships inform the ways that individuals form close bonds, and they determine the way that NPC romances (a common thing in TTRPGs) might play out. Parenting tells us about the values and expectations placed on people in society, and the have a big impact on the way adolescent characters (also very common in TTRPGs) view the world. Funeral rites imply a lot about how different groups perceive death and legacy, and they can guide how scenes with the loss of a character (very common in TTRPGs) may occur. Similarly, gender will tell us how society treats individuals and how people define themselves, and they allow players to design characters with more freedom (a meaningful element of TTRPGs). So let's get started: how do the different groups in my homebrew setting think about gender?
