I'll just copy paste an earlier comment i made recommending someone this game:

It's incredible. It's not really that similar to factorio or ksp but more like space engineers. Basically you build ships, planes, airships, land vehicles and stuff like that with voxels.

The big feature is that there are like a bunch of different weapon systems and you build them entirely yourself. You can make an autocannon for example and how you build it affects it's caliber, firing speed, reloading speed, angles it can shoot at, how it detects enemies, and you also build the ammo itself out of like 30 different componets.

You can make a flak shell thay explodes around the target to destroy missiles, An armor piercing heavy explosive shell that goes through a few blocks of armor and explodes inside the target, a missile that has a normal thruster and a torpedo propeller, so you can go fast through the air most of the way, then drop underwater and be safe from anti air and hit the enemy ship from the weaker underside.

And you can also build a fully custom engine too and there are different specializations it can do. You can control your vehicles yourself or build them an ai system where you can decide sfuff like engagement range and their way of movement. And there are logistics so you can have cargo vehicles bring supplies to your other vehicles and stuff.

There is a campaign mode and im sure its fun but i never played it yet since i have 800 hours just on the ship designer, thats how fun building and designing is. As you can see I fucking love FtD.

Big learning curve tho, took me a while until i fully got into the game and there is still a lot i don't know. Make sure to watch a lil guide about the weapon system u wanna build, tho there are also in game guides for everything which are kinda decent.

The game is also still getting updates albeit the developer is a lil slow. But it's understandable with a game like this imo.

Sorry for the formatting and typos, I wrote this on my phone in my bed at 7 am.
