Harvesting quality fruit grown from quality seed obtained from quality fruit grown from... oh wait.
No quality trees seems to be intentional, as you can obtain all basic materials from them. This would trivialise obtaining legendary Iron, Copper, Plastic and everything made from it. Too OP.

What did I do: with Mech Armor equipped hovered over foundry. At some point my eye caught a slight movement of the minimap. Apparent issue: hovering over a certain area of the foundry causes the up-down movement of the minimap as if the character was constantly moving up and down. Hovering over diff...

Treat it like an organic system - always active.

The first three are all pretty independent of each other, though they all have tools to make the other planets more manageable. Gleba's looking like the hardest planet to tackle but it also benefits less from the other planets, so starting there is fine. Right, so it is indeed intended. The apparen...

Played this since 0.14. I remember my path. First it was "oh, I can Automate things". Then - "wait, why do I need that much stuff?". After - "Now, now I see". Also mods. Since then - 1.6k hours. This is by far the best entertainment/money investment I've ever made.

Is it just me, or the reverse planet order (Gleba - Fulgora - Vulcan) is also viable? I mean, I went first to Gleba for labs, inserters and belts, then Fulgora for EM machines. Ok, so far so good. Found out Fulgora is awesome if you know how to "we do not waste". To do: Vulcan. I feel like...

Trains already scale based on your fuel type, and how big your train network is. 50 trains carrying ore around a large well -signalled network is much more impactful than a single train delivering from a single outpost, especially if you switch from using coal to using rocket or nuclear fuel. Bots ...

Wait, if we take into account new belts and item stacking and quality inserters... having fixed 40 slots per wagon feels somewhat limited. Concerningly limited. I am curious what was the feedback on this during the playtests.

Won't quality take care of this? Quality is ok-ish, but it is a matter of having an upgrade option similar to ones you have in the beginning of the game. You follow sort-of "prototype - industrial - advanced" loop with most machines (drills, assemblers, inserters, and so on). It would fee...

So what exactly you want tier 2 bots or trains to do? As for trains - electrical trains (haven't seen a mod that felt proper yet) or nuclear trains (high capital investment vs. low opex). Wagons - reduced weight/slot ratio (weight/liquid), further improved by quality. Again, there might be other vi...

So what exactly you want tier 2 bots or trains to do? My initial idea for bots is to improve energy/distance ratio, as this value remains mostly unchanged by speed research. Energy capacity is also an option. Another possibility is the "intelligence" of the bots - t1 bots may not have the...

TL;DR As the title says, consider adding a second tier/alternative versions of chemical plants, refineries, trains, roboports/bots and other entities. Why? As of now, there are two progression systems in Factorio. The first one is defined by science - you get burners, then electricity, then chemical...
