A size-tiered mining overhaul for Endless Sky that's out of the ore-dinary.
Seven sizes of asteroid re-balanced across every system in human space. There's a slight buff to mining overall. Large asteroids yield less when cracked with non-mining weapons.
Every mineral gets the full tier treatment. Systems are reclassified into six strata — from picked-over dust clouds to motherlode zones — all while mostly keeping total asteroid counts exactly where vanilla ES has them.
Bigger rocks take proportionally more time to crack, and they sometimes drop a secondary bonus mineral.
There are eleven legendary mining destinations scattered across human space, each with a bespoke asteroid field and a spaceport tip that will direct you there.
Rare groups of massive asteroids wander the galaxy on a 12-day rotation. A prospector named Dusty Vein haunts spaceport bars with tips on where they've drifted.
