I guess you all saw the recent DEVblog?! There was clearly an animated city planet backdrop! I guess our prayers were heard after all!
Scorched? No, I meant this Blogentry: http://playstarbound.com/22nd-january-broom-for-improvement/ I think, this will be either a special "mission" planet, like the outpost/moon, or it will be added as a random biome for the future, but that's just my guess.
That's exciting! I hope this city planet idea is coming. In fact, I'd love to see the various homeworlds too.
Was about to wright a massive post describing what I would like, but saw this. This skips me the effort. It would be absolutely great to have a planet filled with people, something on the 'Extreme' Level, so its more difficult to raid the thing. Perhaps something with superior security, so any aggression results in your death. That way the player cannot farm the resources off the planet. Shield the planetary Shield Generator, Arm security with the best weapons and armor, add shielded turrets, make security teleport in on attack, ETC. Other then that, the planet would supply quests and trading options for the player. Would also be a great place to station the shipyards of Starbound, a place were the ships you pilot are built. I might wright a bigger post later about what I envision a city system like.
After all these years, is this STILL not a thing?! If it is, I'd appreciate being pointed towards this, as I'm looking forward to seeing city planets and such.
