With all the good work doing into designing space maps, I am thinking about what kind of terrains we want. Because terrain changes mess up maps and save games, I want to add as much as possible at once. And I want a set of terrains that will support creative ideas. So, here is a list of changes/additions I am considering. - I want to represent the major moons of Jupiter and Saturn on the map somehow. Maybe as terrain features rather than terrains. - I might collapse all star terrains into "Star", and types of stars (e.g. Red Dwarf, Sun-like, Red Giant, Neutron, ...) would be terrain features. I could add a couple more, such as White Dwarf and Blue Supergiant. - Also an Exoplanet terrain, which several features that could go on it (Rogue Planet, Super Earth, Mini Neptune, ...). - Differentiate between Inner Solar System and Outer Solar System tiles. - More extragalactic terrains and features, representing galaxies, galaxy groups and clusters, superclusters, and voids. Before I do any of this, I'd like to know what TPEHEP and other space map designers would find most valuable for inclusion.
