I get the distinct impression that Sol is very much work in progress. Earth and the terraformed Mars look great, however:
- Other planets seem to be just generated rather than created by hand. Jupiter is just A N other gas giant with wierdly large rings. Io is just a bland ball of rock rather than the technicolour volcano fest it is.
- Many smaller bodies are missing. No Phobos and Deimos, none of the smaller moons around Jupiter and Saturn.
- No space cities

Orbital stations are just the standard Orbis starports (albeit large ones)
