Two points. First, I believe getting started on major industrial production will have a lot of important knock-on effects.
Second, the plan as I am envisoning it already involves spending 4 dice on Nephor II Reconstruction next turn. Neglecting NIM because, "It won't be as impactful because until Nephor II Reconstruction isn't done" seems once again to kinda put things around backward.
The way I see it,
both the SCV factory
and the NIM refurbishment will have a lot of important knock-on effects; it's not a case of one being important when the other isn't. For the kind of specific tasks most needed for huge reconstruction megaprojects, I think the SCVs might actually be immediately more useful, but maybe not, that's speculation.
However, there's an important point hidden in the blurb text of the actions:
[] Nephor II: Planetary Reconstruction (Phase 1) [Reconstruction]
The industrial world of Nephor II was hit hard by the Great War; while the Zerg presence was minimal, the fighting between the Sons and the Confederates was fierce, especially once the factory workers started taking sides. Many of the world's valuable manufactories are in ruins, its hab-blocks burnt out and abandoned, and productivity is at an all-time low. This is not a workable state of affairs; the Dominion needs those factories, and to restart them it needs housing for their workers.
(Progress 0/500, -10R per die)
[] Nephor II: Nephor Industrial Megacomplex (Phase 1) [Reconstruction]
The NIM was the premier mega-factory in all of Confederate space, allegedly superior to even the forge-world of Moria. Now it sits abandoned, partially burnt out, and in need of serious TLC. In truth, despite its shining reputation, the Megacomplex was subject to a substantial diversion of funds and major corruption even prior to the Great War, and its surviving machines are run-down and out of date. A comprehensive reworking is necessary for it to reach anything like its prior claimed output.
(Progress 0/400, -10R per die, Resource income)
...
The Heavy Industry NIM project is about updating, replacing, and reorganizing the mega-factory's facilities. The Infrastructure reconstruction project is about restoring the basic facilities as they already exist. To reach the mega-factory's
claimed prior output (with the clear implication that those claims were significantly exaggerated) will require the NIM project. But to restore the mega-factory's
actual prior output (a less ambitious goal) will clearly require the reconstruction project.
To me, this strongly suggests that bee-lining the NIM project won't get us as far as we'd like. Not because the NIM project is unimportant, but because the infrastructure just isn't there. Because there's no point in putting shiny new machine tools in a factory that has holes in the roof and no utilities connections and no easy immediate way to ship goods off-planet because the spaceport ate a tac nuke during the fighting.
So I suspect that the benefits of NIM refurbishment will be to some extent "strangled" until Nephor reconstruction is complete. First because of "tools to make the tools" issues (many of the machines we want running in the refurbished NIM would themselves best be made at factories on Nephor that are already in need of reconstruction), and second because of general infrastructural deficiencies.
I do not deny that your plan will be working to resolve those issues by working on reconstruction, to be clear, but I do think there is an element of "cart before the horse" at work here.
...
If we had nothing else of comparable importance to do in Heavy Industry, I would nevertheless favor major investments in NIM. I would favor major investments in reconstructing Nephor II regardless, and I do now, and have in the past, quite consistently. But because we have
another heavy industrial investment to make elsewhere that may well prove just as impactful (especially with reconstruction work like the exact work being done on Nephor II), I would tend to favor the SCV factory over NIM
at the present moment.
This is simply because I expect
both the reconstruction project (which I intend to work hard on)
and the NIM project to be impactful, but expect the NIM project not to reach full good effect until after the reconstruction project is done, which means we have a window of opportunity to do other things that are themselves good and impactful.
