Ian Bogost coins the term "procedural rhetoric" as using rule-based logic to further rhetorical arguments. Or as he puts it, "the practice of using processes persuasively."
My big takeaway from this is how Bogost views games as a vector to expose the complexity of social problems that are difficult to express in words or pictures. This should be obvious to any gamer that's picked up Sim City or Dwarf Fortress. Applying it to more topical issues, I wonder what would happen if we gave this generation of school children the Healthcare Cost Simulator just as our generation got Oregon Trail.
