Factorio is the best manufacturing/logistics sim by a huge margin. Some of that is technical things, but the biggest contributor is game balance and the complexity curve. They spent years iterating to find a sweet spot.
It is the best, and the benchmark, for the survivalcraft factory RTS genre. They optimised the game to an absolutely ridiculous degree, that it will even run smooth on a Nintendo Switch.
Probably the best game i am playing, 6000h+ into it now. If you like that type of game, you will love factorio.
Has a free demo on steam, so you can try before you buy.
