The Rules Modification & Design Laboratory
Rules do not merely constrain behavior; rules manufacture incentives. Modify rule variables in real time, run Monte Carlo simulations, and observe how altering a single constraint restructures the emergent world.
RULE MUTATION EXPERIMENT
Remove All Player-to-Player Trading (Autarky Variant)
Catan (Settlers of Catan)
Parameter Overrides
Player Trade Action
Default: Enabled (Bilateral Barter)
Altered: Forbidden (Bank 4:1 / Harbor Only)
Robber Placement
Default: Blocks hex + steals 1 card
Altered: Blocks hex only
Emergent System OutcomesState Machine Converged
Game Duration Shift
+68% (Average match length increases from 65m to 110m)
Strategic Depth Delta
-52% (Collapses social negotiation into raw dice variance)
Observed Human / Agent Behavior:
Players prioritize Harbor vertices above all else; single-resource monopolies on Ore/Wheat guarantee victory.
Strategic Equilibrium Shift:
Transforms a social coordination race into an isolated, high-variance stochastic roll-and-wait exercise.
Core Ludological Lesson:
"Trading is not merely social color in Catan; it is the vital liquidity damper that absorbs dice probability variance."
