## How it works

The repeated accumulation and expenditure of resources links current activity to future possibilities.

## Variants

### Variants and applications

<a id="family-08-variants"></a>

- Constant growth of resources: accumulation itself becomes an observable result <a id="variant-engagement-retention-08-01"></a>
- Income during absence: return is accompanied by receipt of accumulated <a id="variant-engagement-retention-08-02"></a>
- Reinvestment: what you earn increases the speed of your next earnings <a id="variant-engagement-retention-08-03"></a>
- Automation: the player gradually transfers the routine to the system and moves on to control <a id="variant-engagement-retention-08-04"></a>
- Production chains: improving one link creates the next task in another <a id="variant-engagement-retention-08-05"></a>
- Resource bottlenecks: shortage of a specific material directs the next activity <a id="variant-engagement-retention-08-06"></a>
- Prestige and reset for a permanent bonus: a completed cycle turns into the beginning of a more effective one <a id="variant-engagement-retention-08-07"></a>
- Trading and market speculation: price changes create reasons to test the market and make trades <a id="variant-engagement-retention-08-08"></a>

## Context and limits

A map of 160 techniques for analyzing interest, returns, costs and pressure on the player. Involvement in itself does not mean dependence; the presence of separate mechanics does not determine the diagnosis or prove causation. This is the author's classification for critical analysis of design, and not a scientifically established list of the causes of gaming disorder. Assess context, audience, voluntariness of participation, and opportunity to stop.
