To Mr. PlaceMcHolder;
First of all, I would like to thank you for the time and patience you devoted to replying to my post. Your text, therefore, deserves to be answered in detail, incurring the necessary risk of boring the other interlocutors.
About the pirates
When you classify the pirate faction as this loosely ideologically aligned alliance* we have serious narrative bottlenecks. Firstly, as I pointed out in my original post, why would the established factions allow this semi-unified group, hostile to everything and everyone, to exist in the core systems? Even with the collapse of the portals, the 1st and 2nd AI wars, the factions still have enough power and interest to cleanse the core systems of the presence of pirates.
The only plausible justification for this not happening yet is precisely that THE PIRATES ARE NOT A GROUP IN THEMSELVES, but a simplistic classification to designate a faction of "bad guys". It would be like grouping all the insurgents in the world today into a faction called "insurgents", because they oppose the established powers, have a political doctrine that adheres to the use of violence as a strategic way of seizing power and use asymmetric means to achieve their military objectives. This approach completely ignores the reality of the facts, whether an insurgent group is jihadist, or Marxist, whether a group is supported by country A, or country B etc. etc. etc. Let's take the example of Mexico, imagine how absurd it would be to put the Zapatistas and the cartels in the same political macro-group.
The example of Kanta's Den that you mentioned is particularly interesting, because it is the only pirate market that could function as a sort of representative of a pirate macro-faction in the core systems without this making the lore of the game and its mechanics incompatible. I say this because, at the end of the day, Kanta's Den functions as a territory dominated by organized crime (look up black spots and the concept of criminal insurgency) with tentacles throughout the Persian sector.
One possible solution would be to keep this generic pirate faction with only the Kanta's Den market within the core systems (which makes a lot of sense given that the Magec system is populated by smaller factions, such as independents and the Tri-Tachyon corporation.
The other pirate markets present in the core systems would either become other factions or be rewritten to once again make the lore compatible with the game's mechanics.
A quick note: One of my previous posts sheds some light on the pirate issue and another possible solution to the problem.
*"[...] described as being loosely ideologically aligned -- sharing a distaste for the systems of government established & upheld by the major factions, and being far more predatory than most Independent captains. That, coupled with their 'insatiable thirst for freedom and glory,' [sic.] makes it seem to me that Piracy is a distinct anarchic culture/ideology in the sector"
About the independents
I found your position that the independents would be a loosely aligned group, who try to position themselves equidistant between the major factions (Persian League and Hegemony) very interesting. In fact, that would be the solution I would adopt, expanding this with quest lines in the game. I even said in my original post that the independents sound to me like the movement of non-aligned countries during the cold war. The problem is that this isn't explored in the game and the independents end up being as generic as the pirates.
Regarding the technical problems of having too many factions in the game, I don't know if the cause of the problem is having multiple factions or new markets. Because the interaction between factions doesn't seem to be very heavy, but rather the monitoring of the movement of fleets and resources between many markets, which occurs when we put faction mods in the game and which differs from what I'm proposing.
On Fleet Strength and Colony Threats
Apparently we agree. There's not much to elaborate on here
About Faction Names
I've already written extensively on the subject in this thread. If you wish, please revisit my most recent posts.
About other suggestions
If you wish, I can write about these other suggestions, although I don't have much time at the moment to develop all these ideas into text. If you'd like, I can talk to you by voice on discord about it, or we could leave it to discuss these ideas in text at some point in the future.
