Good catch! Yes it's about 33% increase.

When bootstrapping, use less crushers with better quality modules and dynamically change the recipe. For example, if you only have 2 legendary quality 3s, you should use them in one crusher and make it handle all the epic recipes, or even the rare ones.

Try to make everything legendary. Start with legendary production buildings, then a team of fully legged legendary spidertrons, then equip them with legendary portable fusion reactors. I'm now trying to produce legendary metallurgic science and the next step is legendary military science.

They changed the rocket fuel recipe to fix a recycling loop. It could be your fuel production using more ammonia starving the ice platform producer?

Not a Factorio dev, but I won't consider WASM for a modding system:

- Bad development ergonomics. You have to compile something else into WASM, so it would be clunky to run something immediate from the map editor.
- Bad performance. WASM trades high interfacing overhead for computational efficiency ...

So you want spoiled fruits to give 100% seeds but the normal processing remains at the same 2% seeds right?
Makes little difference you end up burning seeds anyway and making nutrients just to let them spoil to get spoilage just gives you loads more seeds.
At least you can burn them for energy so ...

I'd suggest something like the spidertron. It was also post-game content that is cool but not necessary.

Maybe instead of palletization, just have a car / tank crane to load / unload vehicles with inventory to / from trains? I mean in real world trains are used to carry cars. Currently cars / tanks can be transported with belts but are really clumsy at it, so it provides a meaningful way to load stuff ...

There was one miniscule change i did inside of the orbital logistics logic which is trying to pair silos with hubs or hubs with cargo landing pads when trying to resolve logistic requests: those requests are usually blocked if a target entity (hub when sending up from silos, cargo landing pad when ...

This is a wild showerthought, but it could be a good incentive to quality science. Instead of or in addition to quality science being more durable, many *techs* could have quality levels that requires science bottles at corresponding quality to research. For example:

- Legendary advanced ...

My save ran at 50-56 UPS on 2.0.69 but got sped up to 60 UPS on 2.0.70.

Just FYI Lua implementation that Factorio uses is publicly available on GitHub: https://github.com/Rseding91/Factorio-Lua

So if you want to search / test for vulnerabilities you can do so :)


Thanks for the link!

The linked code looks vulnerable: https://github.com/Rseding91/Factorio-Lua/blob ...

Despite the wording, it is an issue in the Lua code. I tried the PoC from https://redrays.io/blog/poc-for-cve-2025-49844-cve-2025-46817-and-cve-2025-46818-critical-lua-engine-vulnerabilities/ . Factorio 2.0.70 seems fine. I used this `control.lua` in a newly created scenario:

You want to use a latch between your selector and the assembler, have it latch onto the same recipe until the assembler flashes "finished recipe" for one tick. You only need the recipe signal until the assembler starts working so read-working / a simple timer could work too.

It also seems a lot faster. Is there any unmentioned optimization?

The difference between a simpler setup and full quality isn't big enough for it to matter in a regular playthrough. And as you said, productivity invalidates a lot of the potential gains. There's only so many quality equipment/machines you need, and then the only purpose of quality is science ...

What are you imagining when you say "upgrade"?

Are you looking for gameplay like "Sure, I'll put rare productivity modules in my labs and rare furnaces on my platforms"?

Or are you looking for gameplay like "Okay, all my science is made with rare assemblers with rare productivity modules ...

This is a cool concept. I am not sure why the legendary module should give the same chance for everything though?


Well, my idea is that by the time you have a legendary module, the challenge difficulty should converge to the current state as it's an OK-ish anchor point.


This could be ...

After having played online with a periodically resetting map side by side with my very-late-game legendary megabase, I think I saw quality with a new angle. Currently people rarely bother with uncommon / rare because they have too little payoff for the relative cost. On the contrary, legendary feels ...
