Well a game did this pretty well almost 20 years ago, infact 2 come in mind, first swg. Every so often all ore spots on planets shifted, so ppl had to rescan and move harvesters, maybe not perfect, a bit of tedious buissy work but it shook things up when the rich kids sat on the best spawn and could pay maintenance for years.
Secondly there's a little space game that clearly is an inspiration to DU where mining is not a problem, loads and loads of ore to mine, its the PLAYER driven economy that regulates if ppl bother mining, too much mining prices go down, not enough mining, prices increase.
I don't think there's a stand alone fix for each broken system in DU, it's a complete new vision to how things should work together, and then implementing them that's needed, probably too late for that after 2 launches, maybe should have got the game working and ready in beta, and THEN launch it, but who knows.
What was it Tod Howard said about launching unfinished products? Maybe nq were listening.
