I have noticed a few questions about whether I play the mod "correctly" or if it's just my quirky play style.
Von-Neumann-V
Before having the purple quantum science pack and the conversion recipe, this surface lacks a source of stone. This makes lore-wise sense for sure. I noticed that especially since I use Fulgora's recycler to use the basically free space-category recipes (namely cargo bay, asteroid crusher, asteroid grabber, thrusters) for an endless source of lds, steel, electric motors and processing units. With these, I could get iron, copper, and plastic as base materials, but not stone and therefore concrete.
Question: Is that the intended way?
Suggestion: A way of dumping items, similar to Vulcanus or space, would be helpful if the recycler is not yet unlocked. I would understand if that is intentional, though.
Circa
I mostly ignore the military scrap as the gold-sand, heavy water, and bitumen are sufficient for the ring science pack. For me, that mostly has way too much gold in the mix, so I tend to just throw it away. I even find it strange that there is productivity research for boosting gold production, while I lack sand/glass instead.
Same question: Is that the intended way?
Suggestion: Maybe a glass production tech instead or additionally.
Mirandus
As this place has no surface, the actual production is on Von Neumann V, where electricity and space are endless. Actually, I don't have anything negative to say about this. I like it how it is, so no real question or suggestion so far.
Nix
I haven't actually played much of this planet, as the freezing condition prevented me to rush it. It seems to be nicely from what I have seen.
Although there is no fixed order for Circa, Mirandus and Nix, I have seen it as the last of these three, which I totally like.
Overall
Personally I see it as an easy with powerful rewards (infinite rockets, space platform and their parts, fusion bots). I'd say for some parts maybe too easy, but I call it "convenience" instead.
