About
Save System Patterns
Purpose
Define reliable persistence boundaries, save formats, recovery behavior, and migration policy.
Use When
- the game needs persistent progress or settings
- save corruption risk exists
- schema changes are likely
Inputs
- state ownership map
- progression model
- platform limits
- backward-compatibility expectations
Process
- identify what must persist and when
- design versioning and migration strategy
- handle partial writes, invalid data, and fallback behavior
- separate runtime objects from persistent data representation
- define tests and release gates for save compatibility
Outputs
- save model
- migration strategy
- error-handling policy
- save QA checklist
Quality Bar
- makes ownership, state flow, and failure behavior explicit
- improves maintainability without over-abstracting
- supports testing, debugging, and safe iteration
Common Failure Modes
- coupling systems through hidden globals or timing assumptions
- writing logic that is hard to test or debug
- optimizing the wrong layer before measuring
