My hollow planet is interesting to explore, but maintaining humidity in the interior caverns is more labor-intensive than expected.
The world's five distinct biomes are each masterpieces individually. Integrating them took some terraforming tweaks but the results are wonderful.
My hollow demonstration planet arrived perfectly. The interior cavern system is lit with bioluminescent crystalline formations that shift color with the seasons. It's become the centerpiece of my collection.
The planet meets all specifications and functions well. It's exactly what I ordered, though I perhaps expected something more 'wow' for the investment.
Six months in and the savanna world is self-regulating perfectly. Population dynamics, grazing patterns, water cycles—all stable. Magrathea nailed the ecological modeling.
Hired contractors to operate on what we thought was a quality world. Everything failed. Magrathea refuses accountability. Absolute nightmare.
