This popped into my head this morning while sitting on my "thinking chair" In regards to mining "ore" I know right now its set to be everywhere, and imo it should be, lets assume the kerbals are using advanced nanotech (able to extract useable metals out of all soil), very unkerbal like but it happens, they can just transform matter into matter. My thought was after glancing at the kethane posts and such I saw something about "planet seed". Is there a way to set the "density" of the ore differently for different planets? Density isnt the right word but let me extrapolate, say if Im on kerbal, I can extract ore at a rate of Z per minute. Now say I fly to the dusty lifeless world of Duna, all of a sudden im extracting at 2x Z, dres or moho IMMA GONNA MAKE ALL THE THINGS! This would encourage setting up ship manufacturing on different mineral rich orbital bodies, making some planets more attractive for mineral mining.
