Pretty much the only game I have played in the last 2 years: Factorio (got some 2000 hours in it)
Genre is Sim, strategy, world building, open world.
You need to build and expand factories, combine resources into more complex things, so go from mining coal by hand to launching a rocket to take you to another planet. Then launch X rockets per minute. There is no wrong way to achieve anything, the only thing that is guaranteed is that your solution will not be the best one, someone will always make a better contraption. For the "contraptions", they can be as complex, or simple, as you want them. Optimize speed or efficiency or space usage, whatever you want.
Extremely polished game, friendly devs who listen to their players, implement things they want. (much like the folks here it seems)
Extremely moddable game, tons of mods already exist, from small QoL mods to complete overhauls of the game. Endless possibilities.
And one other thing, be warned: extremely addictive. It is also known as "Cracktorio".
Runs on Windows, Linux and MacOS (Even native on Apple silicone)
