Choreography：What a player actually does
The choreography feature is four steps.
| # | Step | What it is |
|---|---|---|
| 1 | Pick a song | From the tracks in the game |
| 2 | Line up moves | Drag move cards onto a timeline |
| 3 | Set the stage | A stage theme, and the outfit your idol wears on it |
| 4 | Watch | A 15–30 second stage video of your idol doing exactly that |
What matters here is what the player is not asked to do.
- There is no prompt box. Nobody types a description of a dance and hopes.
That’s the whole bet of this project, in a single feature: the player is directing, not prompting.
Most of what we tried didn’t work
We tried four ways. Three failed, each differently and none subtly — wrong order, bodies coming apart, one run that came back as a blank screen. The fourth worked, and it was the plainest of the four. Camera control went the same way: the obvious approach failed, the unglamorous one worked every time.
We’re holding the specifics for the December playbook. But there is a lesson from this week that costs us nothing to give away, and it’s the one we’d actually recommend to anyone generating video:
Never accept anything that just worked once.

Lyrics editing
We’ve been generating song lyrics. They come back listenable but not natural. So, we started rewriting them by hand, and in the rewriting noticed something about our own product.
Picking a reference track from a list is multiple choice. Changing the words is authorship.
That distinction is the difference between a player who used a tool and a player who made a thing, and we want our players to feel the latter one. Also, it’s more likely for them wanting to share the version I had edited myself.
So the lyric-edit step goes into the game.
