Customer reviews
Nothing wrong with it, nothing remarkably right either. It does planetary things very adequately.
The hollow planet option was the best choice I ever made. Exploring the interior caverns with their crystal formations is like being inside a geode the size of a world.
The sentient-moon system is intelligent but opinionated. We clash philosophically more than I'd like, but it's growing on me.
