The finest game writing is often invisible: a ransacked house that tells you what happened without dialogue, an NPC's animation cycle that reveals their emotional state, a letter found in a drawer that recontextualizes someone you thought you understood. Red Dead Redemption 2 is a masterclass in environmental storytelling — Arthur Morgan's camp relationships are written more in daily interactions and ambient dialogue than in cutscenes.

Baldur's Gate 3's dialogue system, which tracks hundreds of variables and adjusts companion and NPC responses accordingly, represents the current state-of-the-art in reactive game writing. When a companion references something specific you did three hours ago, the writing creates a feeling of genuine relationship rather than scripted interaction. That reactivity is expensive to produce and transformative when done well.

The hardest writing problem in games is giving a player-driven protagonist interiority — internal life — without overriding the player's sense of agency. Disco Elysium solves this by making the protagonist's inner voices the game's skill system. Red Dead 2 solves it through Arthur's journal, which updates in his voice throughout the game. Both techniques create a character who feels like they have a psychology independent of player choice.
