Houses of one are allowed to be elevated, under the provision they choose an extra person to join them. I have already outlined my reasons for including that clause, though it is not steadfast. It doesn't prevent anyone outside of the three noble houses from becoming noble.
I suppose I can ask you from your personal experience: what does a large region look like? How much activity is sufficient? What does a group/family structure look like in such a large region? I imagine you perceived all of those to exist in XKI when you were a member (or at least an ambassador, if I recall correctly, something dealing with extended time in the region). And most importantly, why do said structures work in large regions and fail in moderately-sized regions? I would have thought we are a big enough community.
The first was correct, as I was a member of 10KI before I was a member here. In 10KI, it's tricky. They do have elections for certain areas, but they have no UH/OH type of structure: The forum is ran by 9 people in something called the Council of Nine...which includes Grub in that list.
They have e Delegate, 4 senators, the founder himself, and 3 other roles which make it up. While 3 of those roles are given by Grub himself, the other 5 are through elections similar to ours: Interested members express their interest if they have the correct credentials (which are a bit more strict than ours which let anyone and their mother campaign), and they may/may not represent a current party...though party members usually receive more support. Everyone votes, and the person with the most votes is elected.
The 4 senators control different parts of the forums. One oversees the houses, which have their own forum and are generally pretty active...though outside of occasional competitions usually don't have an essential purpose...much like ours. Another senator oversees the political parties, which again each have their own areas, locked to all but those in that party. The third oversees and runs their lottery system that they have, since they have a currency implemented. The last mimicks the Ministry of Information in which they're responsible for the regional updates that end up being sent to the delegate each month.
There's also Ministers and whatnot, I believe they're the other 3 roles I'm thinking of in the Co9 makeup.
A difference between our elections and theirs are that any of their government roles require a one-region only type of deal, meaning you wouldn't be able to seek a political stand in another region...whereas we allow any of our UH or OH candidates to jump into elections in other regions...we're just against dual cabinet-type duties, which any of the positions there pretty much mimic.
----------------------------
As for your next question, substantial activity to me means that we don't begin losing our shit if there's a sudden blip in activity because people get busy. After all, we'd be active enough to where it'd barely be noticeable, as opposed to become a wasteland until certain people return.
Right now, that's where Wintreath is at. Look at how much things dropped and how concerned people became when a couple of people disappeared. How much people were worrying when Laurentus and PB disappeared and Werewolf went on a sudden standby. That right there tells me that activity isn't at a good enough level to consider something which would require a large chunk of activity to succeed. People disappear without warning, it happens. Until we're at a point to where that doesn't become such a concern as to whether we're going to continue thriving as a region, we're not at a place to implement anything that could potentially backfire on us.
To answer a comment that may come up about the concern being related to Werewolf, my concern is that we wouldn't be incredibly panicked about this were we in a better activity state because there'd be multiple games (not Werewolf, but multiple games of different types) running that people could play while they waited...as opposed to Werewolf literally being the only game we have running at the moment.
---------------------------------
In your third question, the house system in 10KI and in Albion very much mimics ours right now, to where they have little purpose outside of being a place for people to join. 10KI's have a forum specifically for them, to where people can chat in their house to the other members. In Albion it's more sporadic like ours to where there's no set place, but they're just there. But the member counts are substantially higher...in Albion more because they deal with more relationships and marrying and whatnot to where families cross (and their own family tree is really confusing). In 10KI it's member count where the house I was in, for example, has over 30 total members that were part of it, and 10 active ones still. The largest one has almost thrice that total, and over 20+ active members.
------------------------------------
To answer your last question, it falls to activity. This structure would work in 10KI or Albion because they have the activity to back it. As I mentioned, a couple of people could leave, and they'd be perfectly alright because it wouldn't affect them. Whereas if a couple of active members here suddenly went inactive, as evidence has shown in both our history and in recent times, things get really dead around here aside from a couple of topics. Even the IRC has suffered when people leave.
So until that's remedied, we need to focus on that before we shift to something that'll require even more activity.
