Each overview separates player actions, state changes and alternative rules. Examples are hypothetical design scenarios, not claims about a named game. A prototype check states an observable question for the next iteration. Existing detailed references remain separately linked from the direction map. ## Mechanics and variants ### 1. Interrogation, testimony and contradictions id: t191 canonicalId: narrative-investigation--t191 url: https://gamemechanics.pro/en/mechanics/narrative-investigation/#t191 Testimony becomes a set of testable claims; the player seeks incompatibilities with other claims and known facts. #### Mechanic variants - Clarification narrows an ambiguous statement. - Contradictions connect incompatible accounts. - Presenting evidence tests a specific clue's relevance. - Repeated questions account for a witness's new knowledge. Design example: A witness claims to have heard a bell while a repair log shows it had been removed. Prototype check: Test whether a player can explain a contradiction rather than merely guess the intended pair of buttons. - [inkle: ink](https://github.com/inkle/ink) ### 2. Finding, connecting and presenting evidence id: t192 canonicalId: narrative-investigation--t192 url: https://gamemechanics.pro/en/mechanics/narrative-investigation/#t192 Evidence gains meaning through provenance, comparison and presentation within a relevant test context. #### Mechanic variants - Provenance distinguishes findings from hearsay. - Comparison tests shared properties of samples. - Chains connect independent facts into a conclusion. - Presentation changes access to new information. Design example: Fabric matches a repaired cloak and a photograph shows who wore it on the relevant day. Prototype check: Test conclusions with one clue removed and distinguish proof, suspicion and an unsupported hypothesis. - [inkle: ink](https://github.com/inkle/ink) ### 3. Reconstructing events and causal relationships id: t193 canonicalId: narrative-investigation--t193 url: https://gamemechanics.pro/en/mechanics/narrative-investigation/#t193 Reconstruction restores event sequences and causal dependencies, supporting tests of several explanations for the same traces. #### Mechanic variants - Timelines constrain possible event order. - Object placement suggests a feasible action. - Experiments test a hypothesis's physical feasibility. - Alternatives explain the same trace differently. Design example: A fallen shelf could have broken a window before a person left or after a timer activated. Prototype check: Test that the final account requires causal explanation rather than merely sorting every event by time. - [inkle: ink](https://github.com/inkle/ink) ### 4. Procedural stories and drama systems id: t195 canonicalId: narrative-investigation--t195 url: https://gamemechanics.pro/en/mechanics/narrative-investigation/#t195 A drama system selects events from character states and unresolved conflicts to maintain narrative causality. #### Mechanic variants - Preconditions permit events only in suitable states. - Motives explain a character's chosen action. - Consequences change available subsequent events. - Memory preserves previously revealed conflicts. Design example: A neighbor who loses a job asks for help only from someone previously trusted. Prototype check: Test long event chains against established knowledge, relationships and irreversible actions. - [inkle: ink](https://github.com/inkle/ink) ### 5. Role-playing improvisation and collaborative storytelling id: t196 canonicalId: narrative-investigation--t196 url: https://gamemechanics.pro/en/mechanics/narrative-investigation/#t196 Participants propose actions and world details while agreed rules determine what becomes a shared story fact. #### Mechanic variants - Roles grant authority over specific fact types. - Resolution rules settle contested action outcomes. - Scene handoffs change the active narrator. - Content boundaries are agreed before continuing. Design example: One player describes a threat, another chooses a hero's response and a third applies the consequence rule. Prototype check: Test conflicting proposals so participants know who decides and how an uncomfortable scene can be revised. - [inkle: ink](https://github.com/inkle/ink) ### 6. Unreliable narrators and testing interpretations id: t197 canonicalId: narrative-investigation--t197 url: https://gamemechanics.pro/en/mechanics/narrative-investigation/#t197 Unreliable reports require comparison with independent signs and revision of trust in their source. #### Mechanic variants - Limited memory leaves recognizable gaps. - Self-interest distorts which facts are reported. - Another viewpoint reveals an omitted event. - Corroboration raises trust in a particular claim. Design example: A diary describes a victory while damage to the gates suggests its author retreated. Prototype check: Test for observable reasons to doubt before the ending instead of revealing deception only in retrospect. - [inkle: ink](https://github.com/inkle/ink) ### 7. Interactive fiction and text-based actions id: t188 canonicalId: narrative-investigation--t188 url: https://gamemechanics.pro/en/mechanics/narrative-investigation/#t188 Interactive fiction turns reading into an action choice, after which text reports state changes and available continuations. #### Mechanic variants - Links provide explicitly named actions. - Parsers accept a constrained command grammar. - State memory changes familiar place descriptions. - Clarification resolves ambiguous object references. Design example: Inspection reveals a key and a later table description acknowledges the emptied space. Prototype check: Test synonyms, unknown commands and out-of-order actions with state explanations instead of verb guessing. - [inkle: ink](https://github.com/inkle/ink) ## Sources and examples Sources support particular techniques or methodology, not every family variant.
