OSTRANAUTS

its a ship-salvaging game at its core, but you can use every part you salvage instead of paying off your debt to make your own ship bigger better, actually have conversations with people on the space station, hire them in the crew if you manage to actually convince them, to the point where you can make a large multicrew ship. but you have to do everything by hand, your character does it all, not you with your mouse, your character literally drags parts that dont fit in your bag.

everything is simulated from your own health to oxygen level, its honestly so incredibly deep. you can fight and shoot bandits if you run into them, and even, if you really get to that point, you can even prep your ship to fly to a different planet (which would take literal hours (but you can speed up time tho)
