building mini-bubbles along a colonisation path, to support further development / the logistical issue of commodities to drive colonisation further
Though Fleet Carriers will always make this mostly irrelevant.
A freight-fit FC can sustainably deliver over 10000t each day at a distance of 10000LY from the commodity source, for not
that much more direct time investment than would be involved in ferrying 10000t to an adjacent system.
A group using "decommission after delivery" FCs could deliver 10000t per freighter to Beagle Point every two days.
Any group moving fast enough to care about chaining expansions and establishing intermediate points will certainly have enough resources to use FCs to bypass the question; regardless, even if you did need want a supply depot 10000 LY from Sol to ease your attempt to settle somewhere 20000 LY away, the most efficient way to get one would probably be "hope some
other group wants to build a mini-bubble in about the right place" because it'll be ready by the time you really need it [1].
It's a nice idea in principle but short of arbitrarily making colonisation commodities un-FCable (including, probably, carriage on docked ships) I can't see it ever being relevant. With a 10 LY range it's going to take over a year to get more than
one FC jump from the edge of the bubble.
[1] And of course that's the other issue with building your own; you need to build it
big enough for both your needs and those of anyone else settling systems nearby. As the regular Tritium complaints show, getting capacity high enough to satisfy everyone requires a bit more than just a "mini-bubble".
or being able to employ a non-ruling faction as the expansion agent
If you can colonise with any faction in the system, then there are going to be several thousand NPC factions (well over twice the total number of PMFs) usable on day 1.
An adopted NPC faction is far less likely to generate the same level of momentum
No, but that's not the point.
Let's say someone (without a particular BGS faction allegiance) wants to colonise the Veil West Nebula and has the charisma and reach to get other people to join the project.
There's a good chance that the faction they pick will just be "whatever one controls the bubble system closest to Veil West". Is it statistically likely that this will be "someone else's" PMF? Sure. Why does that matter? They aren't going to sell it as "let's get the Sun Wen Ho Pro-Independent Union out to Veil West", they're going to sell it as "let's build colonies in Veil West because it's pretty" and start from Sun Wen Ho because it happens to be the closest system with both a colonisation contact and a pronouncable name, so happens to use that faction. The "Opening The Veil" squadron doesn't even have a faction attached at first until someone points out that if they do attach the SWHPIU to it they get a bit more info on the systems they pushed to so far.
The really big player groups aren't really big because "Winged Hussars" or "Anti-Xeno Initiative" is a slightly cooler name than "Social Eleu Progressive Party" or "Dukes of Mikunn"; all the rest of the lore, artwork, theming, community, activities, etc. is entirely made up by the players regardless. You don't have to name and brand your colonisation initiative after the random minor faction you happen to be buying colonisation permits from.
One could come up with a few exceptions (hypothetical as well as existing)
Really, I think
most cases are "exceptions" to this reading
- the vast majority of PMFs have pretty generic names, bland "generic mercenary group" backstories, and likely about ten people who care about them.
- the majority of large and memorable player-led initiatives haven't involved PMF expansion (or even touched that closely on the group's PMF)
