Customer reviews
Superb.
The hollow planet's interior caverns flooded unexpectedly during the first season. This required expensive remediation work. Not the experience I expected.
Great experience overall.
As a landscape architect, I've reviewed dozens of terraformed environments. The precision seed distribution and ecological balance here set a new standard. Our clients in the Cassiopeia sector are thrilled.
