FMV is the main gameplay method
The Infectious Madness of Doctor Dekker · The Bunker · Who Pressed Mute on Uncle Marcus? · Contradiction: Spot the Liar!
These are not games that merely drop in a live-action clip now and then. The whole experience depends on filmed performances, with your progress coming from what you notice, ask, or click in the footage.
hard
You solve a mystery by reading documents
The Operator · The Crimson Diamond · Casebook 1899 · Keyword: A Spider's Thread
Instead of chasing clues across a map, these games make paperwork the play space. Reports, transcripts, case files, and scraps of text do most of the storytelling and most of the detective work.
tricky
You read the environment like an instrument panel
In Other Waters · Nauticrawl · Objects in Space · Duskers
These games teach you to interpret screens, pings, gauges, and system readouts before they ever let you feel fully oriented. Understanding the interface is the survival skill.
