Customer reviews
Our independent seismic survey found no concerning features. The planet is genuinely stable for long-term habitation and development. Magrathea's specifications are trustworthy.
The sentient atmosphere on my world is more demanding than helpful. It requires constant interaction and attention that I simply don't have time for.
My hollow planet is interesting to explore, but maintaining humidity in the interior caverns is more labor-intensive than expected.
My alpine crystalline peaks are crumbling. The crystal lattice structure was flawed from the beginning and the geological instability makes the world literally dangerous. This is unacceptable for the price paid.
Great experience overall.
