Customer reviews
Works well but requires constant attention to atmospheric systems. It's stable, just not as passive as advertised. Fine for serious operators.
Great experience overall.
The precision and attention to detail in every system reminded me of home. Specifications matched documentation exactly. This is how terraforming should work.
