Take one ride.
As an example, let's take a roller coaster in the dark. We'll look at five ways to build it. What changes is what it asks of the rider.
Some experiences are only meant to "work." Some are meant to stay with people. A checkout line doesn't need to change your life. But a film, a ride, or an event… well, it might.
These aren't five grades of quality. They're five different things an experience can ask of the person inside it.
Enactment
Strike
What did the person actually have to do?
There is a handle in front of you, and something in the tunnel happens because you pulled it. Right now you are conveyed. You are cargo with a good view.
Almost nothing. That is why most rides rightly live here.
Recognition
Light
What did they see about themselves that they walked in with?
At the exit it tells you that you braced eleven seconds before the first drop. You did the same thing last time. Nobody else saw it. The dark is why.
A little attention, and one honest moment at the exit.
Encounter
Heat
What did they reach for that did not work in here?
Bracing is the move. Grip, endure, wait for the end. It has worked on every ride ever built. Here the car does not move again until you say something out loud, in the dark, to the stranger next to you.
This one is real. Fewer riders get through, and some cars will stall. You need a graceful way out for anyone not willing to play.
Release
Ash
What did they get to stop being for a while?
You are cast as someone you would never pick, and you put on a mask before you board. For four minutes nobody can see who you are, including you. Anonymity is one of the best conditions in this entire industry and almost nobody uses it.
People have to agree to this before they board.
Integration
Ember
What left with them that is still running a week later?
You put something of your own into the dark at the start and it comes back to you at the exit, changed by what happened in between. Not a photo. Not merchandise.
The furthest in, and the least controllable, because the rider finishes it themselves. Nobody has built this in a coaster yet.
The useful question isn't "How deep can we go?" It's "Which depth are we building for?"
Choose it at the start. Then, when someone asks "Are we done yet?", you don't have to buy more time by saying "Trust me." You can say:
"We're building for Encounter. Here's what this version asks of people. Here's what still has to change."
The Five Depths don't tell you what's better. They help you compare the experience you intended with the one you actually built.
Sometimes a project stops exactly where it should.
Sometimes it got hijacked by someone needing an answer before it was ready.
Try it on the project on your desk right now. Which depth were you aiming for? Which depth is it actually at?
