Quest Journal
A quest journal records what characters have told the player, tracking objectives, leads and completion states so several storylines can be followed at once without keeping notes on paper.
Conversations and events write entries into a list openable at any time: who asked, for what, where, and what has been done so far. Entries update as circumstances change and move to a completed section once resolved. Most journals separate central threads from optional ones, and many quote the original dialogue, so the log doubles as a record of who said what and how trustworthy they seemed at the time.
BioWare built one into Baldur's Gate in 1998, when computer role-playing games were opening outward: dozens of concurrent leads, a large map, and no fixed order in which to pursue them. Before that, players kept written notes, a practice carried over from tabletop play and adventure games. Automating it was less a creative leap than an admission that a design with forty open threads cannot rely on anyone's memory.
Nonlinear questing became practical, and the journal grew into the scheduling interface for entire open worlds. Costs are subtle. A log that states objectives plainly discourages listening, since the answer will be written down regardless, and it nudges writers toward instructions rather than conversation. Certain games now offer journals that record only what was said, without directions, precisely to hand attention back to the fiction.
