Claude Opus 5 helped me build this partial list

Cannot be emptied: 106 types
The game refuses to start without at least one prototype of each of these.
accumulator, arithmetic-combinator, arrow, artillery-turret, artillery-wagon, beacon, blueprint, boiler, burner-generator, car, cargo-wagon ...

I think a worse case scenario is the fish breeding receipe because instead of 30 nutrient it requires 100, which makes the stack size of 5 insufficent to maintain the biochamber fully running. Nutrient economy on Nauvis is very different from nutrient economy on Gleba. On Gleba your best nutrient ...

Biochambers do not produce pollution but actually REMOVES it during their normal activity on Nauvis, when you cap their efficency with module, you also reduce this effect which is proportionnal to their energy consumption. If you want to keep low pollution generation, it appear counter ...

As in title, I can't get quality fish (entity) by any means I know of. I've tried the following:


Placing legendary fish in water with the drop keybind (z)
Script creating fish with the following command: /c game.surfaces[1].create_entity{name = "fish", quality = "legendary, position = {0, 0 ...

Changes

Added several new notes to Miscellaneous Programmable speaker instrument. (https://forums.factorio.com/134325)
Renamed `Global` Programmable speaker playback mode to `Universe`. (https://forums.factorio.com/134370)
Blueprint parametrisation allows selecting recipe product as dependant ...

Can you elaborate, please? I have some questions to the SA expansion too and base game is arguably more dense and well-thought to me, but I wonder what makes you unhappy about it.


I've written stuff elsewhere. This won't be comprehensive, but is an attempt to summarize and give some examples to ...

Modding

Added mod dependency modifier "+", which marks the mod as optional but recommended. Mod gets enabled by default but can be turned off.
[space-age] Renamed recipe prototypes: "molten-iron" into "iron-ore-melting"; "molten-copper" into "copper-ore-melting".
Reworked recipe categories ...

Features

Added pumpjack and burner mining drill flipping.
Inserters can be flipped to make blueprint flipping reliable.
Circuit connectable entities with control gui on side now have settings groupped into "Input" and "Output" section.
Added option to select which wires (red, green or both ...

Factorio: Space Age — A Late-Game Player's Review

A note before the review: I'm posting this on the Factorio forums because Steam's 8,000-character review limit can't accommodate the full content. My Steam review for the game links here for readers who want the complete write-up. If you arrived ...

Previously - and these recommendations still hold! :-)


Howdy!

The official Space Age Expansion should be mentioned first and foremost as it is implemented as a set of "Official Mods" that enhance the Base Game through additional planets and mechanics. I am assuming that Readers of this Reply ...

As an alternative to the asteroid collector building, it would be nice if asteroid chunks could be picked up by an inserter collecting from the side/front of a space platform. This is the same idea as how inserters collect fish from the water.

The large collection area and central storage of ...

i really love gleba. i might even go there first in my next save, and enjoy the luxury of spidertron and advanced asteroid processing, get an early start on rolling q4 products... get a biter farm going... i've been dreaming of a space platform that imports fruit as freshly as possible, and produces ...

Thank you for this, I tested it yesterday and I got a legendary fish from the rare recipe after ages of not getting a second epic fish :lol:
It took me a while to get through the logic. So I see that you wait for 600 spoilage before activating the spoilage-to-nutrient recipe, but the fish breeder ...

Previous discussion ; see “Overhaul Packs” below. Since this post was originally written the Space Exploration mod has been updated, although I have not tried it myself.

Good Luck!

My take:

A: Space, Fulgora. They have the best recipes in the form of asteroid reprocessing and EM plant, in terms of yield / throughput. Fulgora is also good in the max-rare stage where you can wash for uncommon scrap and rare recycling results.

B: Vulcanus. It has the second-best recipes: lava ...

I don't think you'll like this idea:

Gleba biosulfur.

Join spoilage from overgrowth jellynut soil and bioflux upcycled from capture rockets to make legendary sulfur. As a note: it has to be quality done throughout the process, because if you just just those two upcycles you're probably going to ...

If a inserter found grab a legendary fish into a chest that every slot have a normal fish,
it down quality it and insertet a normal fish instead.
Or a inserter grab a rare iron gear wheel and insert into normal engine unit assembler

maybe also have a option in inserter to disable this feature.

why ...

That's fair, I will just continue to manually insert them. I love having absurd fish ponds.

Thanks for the quick response, this makes total sense, just means it will need to be a janky script implementation, but since someone made a thread, figured its ...
