So here is the general idea of my suggestion. In systems with several solid planets, one or more (depending on the number of planets in the system) of the planet could be "civilized" worlds. Each city world would be "owned" by a specific race and entirely covered in various buildings. Some buildings would be residential, while others would be specific businesses, some special ones dependent on the race. Of course, it would make sense that some worlds wouldn't be populated 100% by its thematic race, as the cities would be fairly large. They would also have the same block protection that mission areas and the current Hylotl underwater towns have. Some examples . . . -Humans There aren't many human settlements outside of the Sol system, so human cities would be a bit rarer than most. They would probably be pretty akin to Earth in the intro sequence. Skyscrapers, skybridges, flying cars in the background, etc.They would be more diverse than most other worlds, with humans still taking up about 40% of the population. -Hylotl They would be pretty similar to the Hylotl cities in the game, but spanning the entirety of the ocean floor and having surface-reaching towers that act as entrances and starports. They would probably be more "sectioned" than the current Hylotl cities, with the residential and business areas not being mixed and in their own separate towers. -Glitch Glitch cities would probably be a mixture of the current glitch villages and castles, as glitch wouldn't make towering skyscrapers like some of the other races. There would also be large areas of farmland and several unique shop types you wouldn't see on other worlds, like a "wizard" selling staves and wands. These are just a few examples. I'm not sure how a Novakid city would work, as they pretty rarely group up to begin with and are said to have no colonized worlds. Anyways, if anybody else has any ideas to add to this, please do so.
