build your dream game

I've watched people make games.
I've made games.
I want more people to make games, and enjoy the process.
This is what AI unlocks.

Fun.

For the player, and for the developer.

• Beats 1–5: name the first five as they pop — the stuff people expect. • Beat 6 (the dump): "...and that's before we get to" — let the avalanche hit. Don't read them. • Beat 7: everything fades, one word left. "None of it ships if it isn't fun. That's the one you can't npm-install." • Land your line: fun for the PLAYER — and for the DEVELOPER. Making it is supposed to be the fun part. • "and that's just to MAKE it." ~50–60s total. ★ BRIDGE INTO THE PREDICTION (this replaces the cut "problem isn't tech" slide — SAY IT, don't skip): "And none of this is because the tech is weak — engines and LLMs are incredibly powerful. They're just built for professionals. So the obvious move is to point a powerful LLM at a powerful engine. Here's why I think that won't work…"

Powerful Engines + Powerful LLMs…
still hard.

Still just a patch connecting two powerful technologies.
You still have to know what to ask for, in the engine's vocabulary.
It regenerates the rules, the logic, the components, every time.
By default, the context is the game engine. Not game design.

To control a character, in a current engine:

Mesh
Renderer
Animator
RigidBody
Collider
Audio Source
…
Movement Logic
Game Rules

In Nereu, there's no manual

Everything is an asset.

Add tags that define what it is: Character Animated CanDoubleJump …

What happens on events: When collects coin

The engine knows how to interpret that, via the systems.

no tags

Matching assets with tags: vehicle, player, driveable

How Bibi drives it

You type"make it shoot"

→

Backend builds a prompt+ live scene context

→

Bibi returns tool callstag_add, rule_create…

→

Handlers edit componentsthe scene updates

How I build Nereu

Me + AI

Nereu + Bibi

↻

Bibi's context is already 3D.

Bibi is the instructions,
not the hands.

World models are a
different medium. Not soon.
