"The alternative is to be didactic. Grab the player's attention, force him to listen to what you have to say. Have the characters talk at his doll. Make them emotional. Make him feel. Didactic art is like a man on a street corner holding up a sign saying Repent Your Sins. It's boring, like school, or a tedious sermon in church. Didactic lecturing doesn't tug on the heart strings in the way that its deliverer intends. And the more he does it, the more the player becomes antipathetic toward the art rather than sympathetic."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
