Looking for games with Deep and Complex Gathering/Crafting systems

[Chaos]

As the title says, I've been looking for some complex and engaging crafting systems that have a high level of complexity and depth. I'm sure it's a pipe dream because most people find them utterly boring but I love a good crafting game.

Let me preface by saying the following games are NOT complex or deep:
Ark Survival
The Forest
No Mans Sky
Valheim
Subnautica

Games that DO have complexity built in as examples:
Factorio
Minecraft (with mods)
Satisfactory

Really something that I can get involved with and learn/discover. I've found a lot of games to just be overly simple and lacking in both content and character, especially if it has halfway decent graphics. There are a few exceptions but they're just that - exceptions.

For those who might be confused when I say Deep/Complex here is a good break down. A deep and complex crafting system has refined products, intermediate products, and end products, with varying ingredient items that may come from many different sources. For example if you wanted to make a circuit board you have to refine copper to make wire, make boards from pressed wood or refined plastic and electronic components, and more just to make a circuit board. Then that circuit board is itself just an ingredient for other items.

If you can craft by radial menu, it's not deep or complex. If anyone has any suggestions I'd love to hear them. Thanks and have fun everyone!

The Witcher oils and potions.

Yatzhee himself coined the expression "PC gaming master race" in reference to the original Witcher's complex crafting and menu systems being unsuited to controllers. Though he later expressed regret over spreading the phrase and had some choice words for single-platform and PC-only snobs as well.

Foxhole
An MMO with a persistent war and a lot of crafting. You could spend the entire game never fighting and gathering/crafting for the war effort. There are a lot of things you can craft from rifles and medkits to entire railway networks with armed trains carrying ammo to the frontline to resupply your tanks and artillery.

Dwarf Fortress
I'm sure you already know about this one, but it is notoriously deep and complex. Some of the complicated projects just get absurdly complex; people have made real working computers inside the game out of pressurized water pumps and minecarts.

Space Engineers
I haven't played this one much aside from screwing around but I believe it is pretty complicated if you actually do the gathering/crafting stuff.

Terraria
Might not be what you're looking for but I think it is worth mentioning. The devs have cared about this game for a loooong time and there is so much stuff in it now.

I don't know. Learn how to save Plump Cap seeds and you're set for life.

The most complex gathering/crafting systems I have seen is in Core Exiles

However that game does not have mass appeal as it not only quite text based but it uses an energy system meaning you can only do so much in any given day. However on the upside it got much more generous energy cap than normal energy based games so you can just stock up energy for the week and play on weekend. There is no FOMO daily grind.

You might enjoy Dyson Sphere Program. It gets pretty ridiculous in its layers of automation. Yet somehow, despite having to be set up manually, and via direct control of an entity, manages to be much more intuitive than a lot of games I've played along its lines.

And I'm loving what they did with the boats

Thanks for the replies everyone!

Foxhole - I'll give it a look as it sounds very interesting. I'm not big into PVP/Combat but that doesn't mean I can't make a weapon to kill the enemy.

Dwarf Fortress - Definitely an amazing game. Had an entire run fail because one of my dwarfs became "inspired" and then went on a rampage because we didn't have the material they wanted to craft with.

Space Engineers wasn't terrible - I spent over 600 hours playing it but meh.

Terraria - Lost way too many hours of my life playing this game repeatedly. Not quite what I'm looking for as it's less crafting and more building but still a whole lot of fun.

Vintage Story - I'll give it a shot and check it out

Dyson Sphere Program - an absolute favorite of mine as well. However I'm still looking for something more crafty and less factory

Thanks for all the feedback!

RimWorld is also a great game but not as complex
