this was in the changes discussion but as it turns out I am making a suggestion out of my answer.
Perhaps an option to make all mineral deposits infinite with the option to choose individually whether they are infinite on planets, moons, and asteroids/comets.
I remember I did once played a game humans only+ spoiler races no NPRs and where I have disabled all mineral techs (capped at 10) and every mineral source found would have to be reduced to 0.1 access and increased to 100,000,000 tons.
The point of the test was not to have mineral difficulties, as after a while in Aurora it hardly is because the issue is mere a logistical one, but to face bottlenecks due to a scarcity of minerals directly in the stockpile.
I don't remember if it ended up because I got bored or because there were too many interruptions...it may have been both.
I think, while having the minerals to mine is a great thing, we should have also some sort of limitation in game to avoid piling up minerals to the point that find new better sources are almost useless. Beware, this is mid game problem as when you grow big then you need access to more minerals either because the one left behind have been depleted or it would take simply too long to transport.
I was thinking maybe we could get a sort of stockpile mechanic? I mean a physical one. So let's say that as we have capped pop related to planets, we could have the same on stock. For instance Luna would be able to "stock" 1,000,000 tons of minerals (you can expand through a dedicated structure) while Mars and Earth more as they are bigger. This would impact the asteroids which are small and making collection centers more of a thing. To reflect Aurora Mineral mechanics the cap should go per mineral and not on the total so the 1,000,000 will be divided by the amount of minerals available and not summed up. So if you have 2 minerals on Luna you will have 500,000+500,000 stock otherwise if you have 10 it will be 100,000 each.
As this could create issues with load and pick, considering we already have the wait until full order an unload until empty one could be added?
