Urban/Wreckage Planets, City adjuster

I recently read what neutrino wrote at one topic:

This give me an 2 ideas:

1. Whole Urban planets containing Land, water and orbital wreckage

2. City adjuster in planet editor. (New biome: City)

1. Metal planets. Unless you mean urban as in TA urban, which might be cool. (See 2)
2. Might be cool. Depends on available time and budget.

He was refereeing to metal planets (which are abandoned Doom-Star-alike spaceships)

Or like Core prime, being urbanized worlds to the extreme.

i like the idea of having cities and other traces of ancient civilization.

I mean planets like urban maps in TA, with some grass or desert

Yeah i would like some remains of ancient cities on my plantes. Or crashed a crashed space ship wreck.

Maybe you can make the buildings or wrecks reclaimeble.
