Before Writing the Plot, Define Who Will Play Your Work and in What Context

The first document when starting an interactive film game should be a “target player context card,” rather than a character biography: who enters the experience, on what device, at what time, with what expectations, and why they stop. Only when that context is clear can the team decide segment length, choice countdowns, subtitle size, save points, and content promises.

“Young players,” “female users,” and “people who like mysteries” are not specific enough. A useful description would look like this: users aged eighteen to thirty-five who use their phones after ten at night, regularly watch short dramas back-to-back, and are willing to make relationship choices but unwilling to learn complex controls. This description can directly change the product, rather than just its promotional copy.

An actionable player context card has at least four parts.

The first is the person. Record their relevant experience rather than demographic labels. For example, “has watched live-action short dramas but has never played a visual novel” explains how thorough the tutorial needs to be better than “a twenty-five-year-old woman.”

The second is the trigger. Why are they opening the experience right now? They might have been drawn in by a clip featuring an actor, received a recommendation from a friend, searched for a particular genre, or downloaded a demo during Steam Next Fest. Different triggers determine how much the player already knows about the work.

The third is constraints. What device do they use, how much uninterrupted time do they have, will they mute the sound, can they maintain a stable internet connection, and do they need to pause? Interactive film games are particularly prone to overlooking the fact that “someone watching a video may not be able to interact at any moment.”

The fourth is the outcome. What do they want to get out of the experience before leaving? It might be solving a puzzle, clarifying a relationship, seeing the consequences of their choices, or reaching an ending worth sharing. The product must be able to deliver the outcome; simply writing “a sense of immersion” is not enough.

The central premise of 《零点回拨》 is phone calls from the future. If the target player is sitting at a computer and hopes to complete an investigation in twenty minutes, the experience can offer call records, access-control logs, and surveillance footage so the player can compare evidence.

If the target player experiences one episode in three minutes on a phone, the design needs to change: an unusual incoming call must appear within the first ten to twenty seconds, each episode should advance just one question, key text must be readable on a small screen, and choices should not require remembering five clues at once.

If the work is aimed at livestream audiences, you also need to consider whether the streamer can explain the options, whether voting time slows the pace, and whether failure endings make for entertaining viewing. The story premise has not changed, but the core loop, interface, and content units have all changed.

Targeting everyone usually means that no single context is properly served. Core mystery players want fair clues and reasoning they can verify; short-drama viewers want to get into the conflict quickly; visual novel players may tolerate large amounts of text but care about character routes; livestream audiences need choices they can discuss.

The first version should choose one primary context and retain at most one compatible context. For example, the primary context could be “completing a twenty-minute mystery experience alone on a PC,” with “a streamer broadcasting it live” as the compatible context. Do not simultaneously promise fragmented mobile viewing, in-depth deduction, group voting in the family living room, and long-form character development.

Accessibility is also part of the usage context, rather than a finishing touch before launch. Xbox’s subtitle and caption guidelines explicitly cover FMV, cutscenes, dialogue, and important audio cues; its time-limit guidelines also remind developers to provide sufficient time or adjustment options for interfaces that require reading and interaction.

First, find five people whose circumstances are close to the target context. You do not need to ask them “Do you like this idea?” Instead, observe their existing behavior: what they have recently played or watched, how long each session lasts, when they quit, whether they use subtitles, and whether they pause to discuss choices.

Then show them a one-sentence premise and a low-fidelity choice, and ask them to explain in their own words, “What am I supposed to do here?” If all five give completely different answers, the problem is usually an unclear player promise rather than the users.

Do not describe a small number of interviews as “users generally believe.” Interviews help uncover contexts and assumptions, rather than prove market size. When you need to assess the market, supplement them with store pages, reviews, searches, and the performance of comparable works.

After completing this card, write the “player promise” needed for the next article. Otherwise, even a compelling story synopsis still cannot tell the team what kind of game to make.
