Realism (of a sort)

[bmills]

It seems to me that when you make a ringworld or sphereworld it should not have any mineral resources. After all, you built it, right? Why would you bury minerals just so you could mine them again? You could make it fertile so it should have good organics, and if the term "radioactives" really means energy sources in general, then these worlds should have high Ratings for their solar collection capability. At any rate, I would like to customize my own games this way. I remember seeing a way to set a planet's initial resource levels in the data files, but now can't find it again. Can somebody tell me where it is?
