Resource regen is configurable so can be adjusted over time…
I was actually considering strip-mining the hell out of an area just to try and sell the basic resources. Not very profitable compared to gems an such, but people will eventually tire of getting their own basic building resources … especially for bigger builds! Although I’m guessing this will not be vey practical in the early game due to weak tools and slower mining.
I’m not really sure whether the resource regen rate needs changing just yet. I guess a more informed decision would come down to how many starting servers there will be at launch, and player populations and dispersal on those worlds.
