Eureka! Oil has been discovered on the island of Catan. The
great engineers of Catan have learned ways to improve production
using this valuable new resource, both by converting it into
other materials and enabling the upgrade of cities into
metropolises. But oil is scarce and its use does not come
without cost. Using oil produces pollution, as well as climate
changing emissions, which bring with them the threat of coastal
flooding—and absolute disaster. With the discovery of oil on
Catan, the Settlers face a new challenge: deciding whether the
common good is worth limiting oil usage or whether the pursuit
of victory is worth the risk of ruin.
