Resource extraction

Map nodes (ore patches, trees, fishing spots, oil wells) hold a resource type and a richness or purity value. An extractor, which is a placed machine, an assigned worker, or the avatar with a tool, produces units at a base rate multiplied by tool tier, worker skill, richness, and modifiers. Output goes to an adjacent buffer or is carried away by hauling. Satisfactory multiplies extraction by node purity (impure 0.5x, normal 1.0x, pure 2.0x); Factorio drills mine a fixed rate per tile with productivity research; RTS games such as Age of Empires assign villagers who gather by walking to nodes and back; Minecraft and Valheim gate which blocks can be mined by tool tier. Inputs: node, extractor, labor or power. Outputs: a stream of raw materials and, where depletion exists, a decrement to the node.

The first link in every chain. Players scout for rich nodes, claim them, and judge how many extractors a site justifies. In avatar games, swinging a tool at a rock is a tactile, repeatable earning loop; in factory games, placing drills on the best patch is an early, high-leverage decision.

• base rate per extractor and tool or tier multipliers
• richness or purity variation across nodes
• labor model: machine, assigned worker, or avatar action
• node placement and distance from base
• whether extraction depletes the node (see deposit depletion) or is infinite

• Uniform nodes make location choice irrelevant.
• Extraction rates far above processing capacity create endless stockpiles and remove pressure.
• Avatar gathering that never automates becomes grind late in a run.

• Rich nodes far from base create a tradeoff between yield and logistics cost.
• Contested nodes become flashpoints in multiplayer and RTS maps.
• Extraction is the root of every production chain, so its rate caps the whole economy.

• Could procedural geology tied to visible terrain features make extraction sites a matter of inference rather than icons?
