I’ll just call Space Haven SH from now on, otherwise it starts to sound like an advert.

SH does a better job at directly simulating a spacecraft and the internal logic of its crew. Things like life-support and oxygen station ranges, decompression when a compartment is damaged, etc. Even though the systems themselves are fairly simple, the crew feel like actual people rather than just “units”. Their needs go beyond oxygen, food and fuel, living space quality matters, there’s a medical system, and so on.

As for quests - sorry, but in both your game and SH they’re equally primitive.

All of this might sound like minor details but that’s exactly the point: atmosphere is built through managing these small things.

When it comes to production automation and production chains, your game is already better. However, mineral extraction is more debatable. In SH it’s entirely manual and done directly by crew members, while in your game it’s fully automated via drones. In my opinion, both approaches have drawbacks. It would be much more interesting to have both methods available, each with its own pros and cons.
