I wonder what percentage of the planet tiles have either been scanned or had at least one node mined from them. This week I've scanned over 100 contiguous tiles on Jago in the middle of the oceans, as far from any markets or obvious settled bases (multiple tiles claimed) as I could. Barely any high end resources and I've mined through at least 6 mega node empty caverns (and those are the ones I've randomly encountered). I kept going further and further to see if I'd get into an untapped area and just fell into another mega node cavern.
The problem with this mining experience is not only is it RNG to get the high end resource you might need, but the odds of finding them continue to decrease with time. We are barely into the launch of the beta here and great swaths of the planets are scanned and cleared of the best resources. Yes, I'm sure there are "many" untapped tiles out there but the odds of finding one are continuing to decline. This is not a good experience and will only get worse over time.
Yes, new planets might help, leaving this system a resource desert. I really think some kind of ground healing, random resource respawn system is needed.
