Game Design Unknown Unknowns Prototyping

Use prototyping to discover what actually needs to be learned.

This skill helps map uncertainty, identify likely blind spots, frame prototype questions, choose the cheapest useful prototype type, sequence tests, and define stop criteria. Keep the work practical and decision-oriented. Do not prototype to mimic production. Prototype to expose uncertainty.

Core principle

Preproduction handles known unknowns. Prototyping explores unknown unknowns.

That distinction matters.

• Known unknowns are questions the team already knows to ask.
• Unknown unknowns are hidden design problems, emergent opportunities, and unexpected interactions that only become visible through testing.

Therefore:

• do not prototype to mimic production
• prototype to expose uncertainty
• prototype to discover what the game might actually be
