## Variants

### Variants and applications

<a id="family-group-22-variants"></a>

- Character rescue. Rule: Liberated residents give rewards, information or new services. <a id="variant-mv-241"></a>
- Side quests. Rule: An optional chain of actions creates an additional research goal. <a id="variant-mv-242"></a>
- NPC movement around the world. Rule: A character's position and availability changes as events unfold. <a id="variant-mv-243"></a>
- Shelter development. Rule: Found residents and resources expand the functions of the central settlement. <a id="variant-mv-244"></a>
- Repair and launch of infrastructure. Rule: A restored device opens up new routes and opportunities. <a id="variant-mv-245"></a>
- Choices with consequences. Rule: The decision changes relationships, the state of the area, or available tasks. <a id="variant-mv-246"></a>
- Reputation and group affiliation. Rule: The attitude of the characters affects the services and conditions of access. <a id="variant-mv-247"></a>
- Limited event. Rule: The encounter or opportunity depends on the current stage of the story. <a id="variant-mv-248"></a>
- Collection of evidence and journal. Rule: Records help restore the structure of the world and find further goals. <a id="variant-mv-249"></a>
- Ecological storytelling. Rule: The location of objects and the consequences of events convey information through research. <a id="variant-mv-250"></a>

## Context and limits

The author's working taxonomy of mechanics, access rules, structural patterns and support systems. This is not an industry standard or a statement that every item is required or present in every game. Hybrids and support are highlighted separately. Any finite list is limited by the level of detail; combinations and new options remain open.
