A game can return in the correct box and still be unusable because one deck, miniature or expansion module is missing. A lending record works best when it captures box contents at handover, not weeks later during inventory.
Hours of painting disappear when an army is shown as one crowded group photo. Unit-level records can reveal color decisions, conversions, characters and narrative without overstating competition results.
A giant lore document can be accurate and still be useless at the table. A living campaign bible separates session-ready facts, unknowns, character relationships and chronology so information can be retrieved during play without spoilers.
