I'm completely hooked on this game.

My buddy and I have been sneaking in some Satisfactory at night when our families are in bed. If it makes it funnier, you can picture it like a secret love affair. Late night messages, slipping in and out bed trying not to wake the wives, and mid-day texts about our big plans (with our factories). Friends, I literally play this game in my head when I'm not able to play for real. And it's just as good since most of it based around planning.

Anyway, I'm surprised by the depth. A lot of it is intentional while a lot of the rest is the natural result of players kind of hacking the build mode to do things you can't normally do such as curves and 1 meter vertical conveyers.

What are your favorite tips and tricks for this game?

I've long enjoyed Foxhole and X4 and was wondering what other games has similar logistical systems. Both give the same satisfying feeling when you look at the big picture of how the games are a complex interplay between the immediate gameplay, and what is being simulated "behind the scenes" to enable it.

The descriptor in the title is a bit of a mouthful, so let's break down what I mean.

Complex
To exclude typical resource game mechanics, where you "just" mine resources which gives you resource points that you can spend directly.

Required & Supporting
In Foxhole the main objective is to push the front and win the war. And players can focus on that and never have to really think about how they get their weapons and ammo. But at the same time the logistics is the entire reason they even can fight.
In X4 you can fly about and do stuff and acquire ships while relying on the AI empires economies. But there has to be some alive economy for the game to not go to a standstill.
In short, logistics systems that are required by the game, but not necessarily by the individual player.
This excludes games where the logistics system is the game, like Factorio, Dyson Sphere Program, Satisfactory, etc.

Real end-2-end
To specify that there should as little cheating as possible. Though obviously there is always some cheating in games. Both in X4 and Foxhole, every resource is tracked right from harvest, to refinement, to the end product. And all steps require real moving of goods by AI (X4) or players (Foxhole) between factories, other intermediaries, and end users.

So what other similar games are there? I was thinking of EVE Online, but I think only the player orgs in null-sec have real economies in that game, and you could still play it if they all suddenly stopped.
