What problem does it solve? Raw game ideas often stay vague, unvalidated, or impossible to scope. This Skill turns loose creative energy into a concrete, market-checked, scope-aware game concept through an interactive seven-phase workflow instead of unstructured brainstorming. ## Core Features & Use Cases - Structured Ideation Phases: Walks through creative discovery, concept generation (verb-first, mashup, MDA-backward), market validation, core loop design, pillars, player type validation, and scope feasibility. - Interactive Questioning: Asks the designer direct questions at every phase rather than generating a concept for them, keeping authorship with the user. - Validation Gates: Applies wishlist, elevator, and comparison tests plus market sizing and competitive analysis before a concept proceeds. - Use Case: A solo developer says "I want to make a game but don't know what kind." The Skill guides them from emotional discovery through a 30-second core loop test to a scoped Game Concept Document with a vertical slice plan. ## Quick Start Ask the assistant to start a game brainstorm session to develop a new game concept from scratch, optionally naming a genre or theme.
