Would like to say that I have serious concerns about ore distribution when the terrain is reset.
As one example. I checked over 100 scans from SInnen and none of them showed any Acanthite.
In the current game with underground mining neighbouring tiles may have lowish levels of acanthite but still worth mining and 3 adjoining tiles might yield 50-60kl. While this isn't a huge amount is a decent drop to top up a factory.
If you need Acanthite currently while it's not easy to find mega nodes there are at least trace amounts in a reasonable number of tiles. The new system seems to be more binary and something is either there or it isn't and the number of tiles with the isn't seems to be far greater and the concept of 'trace amounts' has been thrown away because now with not only need to find a tile with a particular resource, but it has to be there is sufficient quantity to warrant the territory tax, cost of miner, and mining charge to extract.
With seeing how the distribution 'seems' to have emerged I think it needs to be stressed that @NQ you will get one shot at this and it NEEDS to be right otherwise creating even more of a scarcity will have serious ramifications for the players and the economy.
My fears for the future of this game are reinforced by the fact that the PTS has gone live for the 2nd time WITH the same rates/values etc as previously used and nothing has been tuned. The only real difference is that you turned off the air brake collision detection that you were testing. That 'implies' to me that you intend to take the current PTS iteration and apply it to Live with little to no changes.
I would also like to add that while I get frustrated with the current mining some times and do other things instead I am at the same time going to really miss it! For all it's faults and frustrations there is nothing quite as satisfying as getting to the bottom of a mega-node you've just cleared out and looking up at a massive cavern that you've created. Sorry, but asteroid mining really pales in comparison to that.
