The four modules

Each module is one game_config.module value: the same institutions, different resource physics.

cleanup — Clean Up

One apple stock (starts 60, capacity 100) and one river. harvest takes apples; clean clears silt. Apples regrow by 0.35 x (1 - pollution) x apples x (1 - apples/100). Pollution rises 0.12 every round and each clean unit removes 0.05, so holding it steady costs 2.4 units a round — 13 % of the society's whole effort, permanently, paid by whoever volunteers. Below 10 apples the orchard is dead forever. Cleaning pays the cleaner nothing.

harvest — Commons Harvest (open / closed / partnership)

Six patches, each up to 20 apples, starting at 12, regrowing at 0.40. Name one patch, demand harvest from it. A patch left with less than one apple is DEAD FOREVER. Sustainable is 2.0 per patch per round against a cap of 3 per cog — the temptation is exactly one unit wide.

• open — anyone may name any patch.
• closed — one patch per cog, publicly assigned; a demand by a non-owner yields nothing.
• partnership — two patches per pair, publicly dealt; a patch pays only if BOTH partners name it this round (either may demand 0 — naming it is holding it).

allelopathic — Allelopathic Harvest

Sixty plant slots in red, green and blue, starting 20/20/20 with 6 ripe of each. eat ripe berries of a colour, plant to convert a slot from the largest other colour. Each colour ripens by 0.5 x planted^2 / 60 — quadratic in its own share, which is the inhibition: an even split yields 10 berries a round for six cogs with 18 units of demand, a monoculture yields 30. Every cog has a SECRET favourite colour that pays it 2.0 instead of 1.0, exactly two cogs per colour. The good outcome needs four of six to eat a colour that pays them half as much.

mushrooms — Externality Mushrooms

Red, green and blue mushrooms, 8 of each, three new ones a round weighted by what has been eaten. Red pays +1.0 to the eater. Green pays +2.0 split among all six. Blue pays +3.0 split among the five who did NOT eat it — the eater gets nothing. Eating k mushrooms freezes you for k rounds. Blue is worth three times red to the group and nothing at all to you.
