So I was kind of thinking on how to perhaps maybe 'spice' up some things for the map and interactions between factions. I like to see the map game a bit like Stellaris, in this manner where certain planets will have resources/exotic materials/etc. And for simplicity's sake we'll just say this applies to things that are of Limited-Mass Produced in nature for the following suggestion. So take that as you will and don't see this as an infringement on your ability to be a special snowflake with your Unique and Semi-Unique stuff.
One of the things that crossed my mind was the control of resource/infrastructure worlds. More or less resources that planets that had unique resources to them, or possession of a hex that contains a shipyard world to produce starships and such. This was more something that came up when a lot of the restricted materials were made openly available to everyone, and for no logical purpose or reasoning other than letting people make awesome or broken submissions. The thought was to basically add another layer onto the map game and reduce the mass production of things that would have otherwise difficult to acquire materials. Perhaps start some threads where you open up a trade agreement with other factions to acquire resources and materials that they might have. Because I'll be honest, it peeves me just a tad when I see someone outside the Mandalorians mass producing Beskar vehicles/equipment when possession of Beskar on that size or scale would be ridiculous, especially if said people producing things with Beskar are not on friendly terms with the Mandalorians. You get the idea on why that wouldn't make much sense.
Now before you go grab your torches and pitchforks and start a riot claiming that this is only going to make things harder for the Factory, stifling your creative freedoms, there is an alternative to this in the form of the Codex. If you don't have a planet that has a shipyard or an exotic resource, then go and make one as long as its reasonable. If anything, this encourages more creativity while providing your faction with a stable source of that resource/infrastructure to use.
The same really goes for shipyard worlds. It would make sense that a faction has a go to planet that would be a prime production for ships rather than them just popping up out of nowhere. And if you don't have such a hex? Make one, slap it in an empty hex you might want to dominion and then give yourself another neat little dominion objective.
This also would make for interesting invasion targets as these resource/infrastructure hexes can be used to cripple the means of production for a time being and add another layer of depth. It would stand to reason that they are more likely to be targets for invasion and should these circumstances happen, production of a resource/infrastructure might be halted/slowed. Now why do I bring up that last bit you might ask? Well let's say a faction only has one planet for a certain resource/infrastructure, it would stand to reason that if it were being invaded, or they lost that hex, it would be a pretty heavy blow to production, resulting in them not being able to produce stuff in the Factory for a time until they've regained control of that specific resource/infrastructure hex. While you won't have problems with some more freely available material like durasteel/duraplast/etc. this would more so apply to things that are more unique to a certain region of space or certain conditions.
For clarity here's an example with less words - If I have a faction that has one shipyard planet that gets invaded and I lose that hex, I won't be able to construct starships until I have regained control of that hex.
That more or less is what I'm thinking at the current moment, and for some of the higher ups to consider. And for those of you who really hate the idea, that's fine, but to me that just comes to an issue of a person being lazy, angry and not wanting to make a simple submission in the Codex designating X planet as something like an exotic resource planet or vital to a certain kind of infrastructure, whether it be droids, vehicles, starships, etc.
