Interpretation of data is a keystone of gaming. Weekly, we transmute the results of dice into stories. A feature less rare in modern writing is the move from pure data to signs and codes as the subject of interpretation. We've all come across games based on tarot decks or using codified phrases, for example.
My query is thus: How symbolic/esoteric/emotive/vague can interpretives be before they become useless to gameplay?
If say, we were to draw Hanafuda cards
to resolve/create in a hypothetical game, would we attempt to define the symbolism, gauge an emotive-response or just go off an action suggested by the aesthetic?
What if it I got a blank die and drew one on each side: a line, a loop, a chevron, a ring, a solid circle and a violent squiggle. Useless?
Sorry for my odd measure, I think I have a fever.
