I was 100 perfect serious about getting rid of subfactions, pretty much for the reasons Gerwald listed, and even more so for the reasons people say they’re good.
1. They limit interactions between broader groups of people, which is how we run into problems of antagonism and power fantasies, because we don’t see the people behind the characters. So of course it seems like they don’t care about the story, they’re just an Enemy to be defeated. If they didn’t care about story, they wouldn’t be on a writing forum, and probably wouldn’t last very long. The fact is their idea of story is probably just different, which is best mitigated by taking to them and engaging with people outside the faction bubble. Subfactions make it unnecessary and further isolate the walls between groups.
2. They’re basically monopolies. Diversity of ideas and groups are good! It’s what makes the flourish and helps everyone find their own sort of place. No subfactions means more minor factions, which means more activity, generally. With subfactions, however, the smaller, more niche areas that would traditionally be a minor faction (like a criminal organization or a rebel faction or an academic faction or an exploring faction) is more or less subsumed by the major faction. Essentially, you have the big chain stores buying up the local mom and pop shops, dictating how they function, what they do, and their culture, when really, they are separate and distinct groups that should stand on their own.
3. Yes, it dilutes the major faction identity to essentially becoming just, we all like writing together so we’ll do everything together, even if other people are doing the same thing already. A friend group can have multiple separate factions ongoing. They don’t all need to be the same one.
4. Imma be real with y’all, I grew up in American fundie-lite evangelicalism. Making tons of subgroups to do different things with the same people is the exact same dynamic. It doesn’t make things better. It created echo chambers super rigid and in-group/out-group divides. Contrary to what everyone told me growing up, it doesn’t actually make life, or stories, better. They get stale because there are no new fresh ideas, no new fresh perspectives, no fresh energy, or anything to keep a group vibrant or thriving over time.
5. Subfactions are not the same as faction groups. By this, I mean, that a subfaction usually has a distinct identity entirely separate from the hosting major faction. Their themes are different, their focus is different, the genres can even be different, and their stories can be fundamentally different. That’s not the same as a Jedi Order, a Clone Army, a Republic Navy, and a Senate all being in the same faction, because those are all very closely tied together. I mentioned a few years back how factions are like dnd campaigns, and people didn’t like that. But I still stick with it. Each faction is telling its own narrative, even via different groups. A subfaction is essentially a separate campaign narrative. Like my League, for example, has politicians, free traders, mystics, rangers, etc. They’re all part of the same narrative of generally heroic, if perhaps chaotic and legally ambiguous people, trying to make the Outer Rim a better place for people to live. Of course there’s different archetypes, but they all form a semi cohesive narrative arc. If I went and made a crusading Mandalorian subfaction, that would be a huge tonal, thematic, and narrative shift. It wouldn’t be a cohesive identity outside the same writers. It would be better to spin that off into its own faction. Of course there’s different groups within major factions. They’re usually more or less governments of some sort or another, or at least some sort of society, which has various groups. But that doesn’t make Jedi Sentinels a subfaction of the Jedi Order, for one example. They’re just a somewhat different perspective on the overall Jedi narrative.
And yea, I can definitely agree with Srina that the pressure for numbers of members and posts plays a big part of it. I considered making subfactions in the League to try and bring in more people to have more activity. It’s a quick and seemingly easy way to boost those, but I don’t think it would have helped the faction any in tbe long run to maintain the stories I initially wanted to tell. So if we can end that pressure, I think we’ll be much better off letting there be more diverse factions doing different things than essentially consolidating everything under a few major factions.
