Wow this game is better than I expected! It is basically Factorio and Minecraft combined. You search for resources all over the world and then set up mines on them and have to power the mines with coal or electricity, and then you transport the materials to a forge etc. You can set a miner on a patch of coal, then have it send the coal to a storage crate but some of it back to a hopper that powers an electric engine to give you endless coal.
But there is way more stuff to research than Factorio so this is a really long term game. I put something like 15 hours in so far and still only scratching the very early surface. There are a lot more resources, for example I started with coal, tin, copper, and iron, but I also needed lithium for more advanced stuff like battery packs, and that is really deep underground. So I had to build a huge mine tunnel, far deeper than you ever go in minecraft, and then I had to build down there which requires setting up a power network etc. It is really addictive, I loved the way Minecraft looked and felt but I always got super bored because there was no purpose to building anything. This game has lots of purpose, you have a huge research tree to work through and everything you want to make, requires components, and getting those requires expanding your factory network far and wide.
I haven't even started with the combat yet. There is an item you can build called a Threat Scanner, and once you build that it will trigger the attacks which are like Factorio, not too deadly but you can't ignore them. I want to do that but I wanted to get the basics down first and it has taken me a long time to figure everything out and get a basic base setup. I loved Factorio but only until the research was done and then I got instantly bored. This game is the same kind of experience but has a lot more length to it. I think it is maybe more satisfying too because you are IN the world, in first person, so you everything you build up close and personal. Also it isn't 2d, some veins of metals are on the surface but lots of stuff requires digging, and you need to make serious mine shafts for that. The bottom of the world is many times deeper than Minecraft goes.
Also you get a grappling hook which is a big part of the game, and flying around with that is so satisfying... It is an essential way to travel up your deep mine shafts and over long distances, but it is also really fun. So glad I heard about this game, it seems like hardly anyone knows about it.
