I heard that there's going to be a major overhaul of the planet management screen before the final release. I'm not sure what the plans for that are, but if it's not too late I've got an idea about it.
Taking the place of the existing map, the actual spherical planet would be the interface. Like in Google Earth or Star Chart rotating the planet would be the way get to different areas of it.
Instead of hexagonal tiles where one building can be placed. I'm thinking there should more organic boundaries between regions, where regions are more than just one hexagon on the planet and those regions can have/build more buildings than one at a time. (The hexagons would probably be smaller)
Lastly, it might be cool to have these "organic" regions grow and divide as the planet's population grows. Also, now that the actual planet would be the interface the player would see and interact the regions from orbit instead of tiles with building icons.
I'm not sure what modifications like these would do to the gameplay, but I think it would make planet management more fun and realistic. Adjacent bonuses could be replaced by having certain buildings in the same region (where regions have a limited number of buildings) and players might make choices between surface usage or population density (where higher population density allows more buildings in a region and surface usage creates more regions with lower building limits).
What are the plans for the planet screen by the way and what do you think of this idea?
