Shared contributions and private goals
Private resources advance personal goals; shared contributions protect everyone. Others' contributions and their visibility change cooperation and free-riding incentives.
The player's decision
Keep resources assuming others will fill the gap, or contribute now to reduce shared failure risk?
Original scenario
Original setup: three players hold four wood each; a shared bridge needs six. Saved wood decorates private gardens, but no bridge means no deliveries. Aggregate and individual disclosure differ.
Start with this prototype
Build three local roles, three rounds and public/private goals with two disclosure modes. Show contributions and shared outcomes, then review decisions without personality judgments. Exclude real money and social reputation.
Change one variable
Vary public thresholds and private rewards separately to identify always-contribute or never-contribute cases.
What to observe in a playtest
Are resources conserved, and does anonymous contribution avoid accidental individual disclosure?
Take the full design card

Original analysis · version 1
Common pitfall
Treating non-contribution as a moral failure hides incentives. Explain information and consequences rather than shaming players.
Observations and sources
Cases refer to public documentation. Developers and community wikis are credited separately; document review is not a claim of hands-on testing.
- Eco
Production, laws and ecological consequences connect individual needs with community survival.
- Dead of Winter
Colony objectives coexist with private secret objectives, separating group success from individual victory.
