Culture charts are about format lifecycles. A physical product appears, grows, saturates and then collapses — but the shape and timing of the collapse are rarely what a reasonable person would predict. Vinyl did not die; it became a collector's object and then grew again. Cinema admissions kept falling even when blockbusters kept growing. Cassettes came back as a niche joke that turned into real numbers.
Extraplot's culture charts are built from published industry totals and hand-checked before they enter the bank. They are not about which film was best. They are about what the market did over time, and where the line turned.
What kinds of charts appear
- Format wars: physical versus digital, streaming versus downloads, rental versus ownership.
- Platform lifecycles: console generations, store counts, subscriber growth.
- Industry totals: box office, music revenue, cinema admissions.
- Resurrections: formats that were supposed to be dead and were not.
How scoring behaves on culture charts
Culture series include the most dramatic shapes in the game. A collapse can lose 60% in five years; a revival can come from near-zero. That makes them hard to draw loosely and very satisfying to get right. It also means the visible slope can be a lie: a curve that looks like continued growth may be a year from its peak, and a line that looks dead may have already bottomed out.
The game filters charts where flat or trend lines work well, so a culture chart in a daily set usually hides a turn, a plateau or a second act. Look for units and scale first: a market measured in billions of dollars is not moving at the same speed as one measured in thousands of units.
Drawing advice for culture charts
- Decide whether the visible trend is a growth curve or the middle of an S-curve. Most format adoptions saturate.
- Physical formats collapse faster after their peak than they grew before it. Digital ones often keep growing longer than expected.
- A revival is usually small in absolute terms. Do not draw a dead format returning to its former dominance.
- Industry totals and company revenues move differently; read which one you are drawing.
- When the cut-off is near the present, remember that a full year of data may not exist yet for the final year — the bank uses complete years.
Why culture charts are the most argumentative
Everyone has opinions about culture. That makes this category the most likely place for a player to be furious at the reveal — and the most useful for recalibrating intuition. It is easy to remember a cultural moment and hard to guess its size in the data. The gap between the two is the whole game.
Culture charts also show up in daily sets as the middle charts, where the visible trend is real but the bend is not obvious. They are rarely the warm-up, because the shapes are too active, and rarely the bold call, because a format collapse is usually visible before the cut.
