Customer reviews
The purple-sky nebula effect they created for my world is hypnotic. Standing on the surface and gazing up feels like floating in space. Simply transcendent.
My hollow planet is interesting to explore, but maintaining humidity in the interior caverns is more labor-intensive than expected.
The redundancy and failsafes are excellent for enterprise use. For smaller operations, it feels somewhat over-specified. Still good value.
