In a recent NPR interview, Ian Bogost of Persuasive Games walked his host through Oil God, which explores the relationship between gas prices, geopolitics, and oil profits:
You are an Oil God! Wreak havoc on the world’s oil supplies by unleashing war and disaster. Bend governments and economies to your will to alter trade practices. Your goal? Double consumer gasoline prices in five years using whatever means necessary.
Ian Bogost gave a longer interview back in June.
