The games

Fourteen games, their rules in content.

Each is a Godot project whose rules are .ledger files, checked by its .play files and run by the kernel, with Godot drawing what the world says. Each was made to put Ledger to a kind of game it hadn't met, so each shows something. Three are shown playing; the rest are listed by what they show.

Survivor

A survivors-like run, from the title to won or lost

Walk, and your weapons strike on their own: a whip, knives, garlic, an orbit and a familiar, each levelled from a pick of three cards, against a crowd that grows until the reaper comes. Each weapon is an ability and its effects in content, with a play beside it that checks what it does.

Moments with no code: a strike, a hurt, a pickup or a level-up is a cue of the Godot kit, bound in the editor to what the world's journal records.
Saves anywhere: F5 and F9 quicksave and quickload mid-run, and F8 writes a recording that plays back to the same state.
Space on the host's helpers: the foes' steps and every search for the nearest foe are Ledger.Host's plane, allocating nothing.

ARPG

Two acts of an action RPG, with eight Exiles to play

Pick an Exile and fight through two acts with skills on the mouse and keys: a Fireball, a Frost Beam held as a channel, a Charged Arrow drawn and loosed, a Cleave, a spear. Gear rolls affixes, skills take support gems, and a passive tree of four branches grows the build. It is the largest content in the lab, written on the cookbook's backbone.

A build on the backbone: affixes, gems and the tree's nodes are modifiers on stats the backbone reads, so asking why a number is what it is names each piece behind it.
Held skills in the cast forms: a channel that pays by the beat and breaks on a heavy hit, and a charge loosed on release.
Flasks on a belt, and quicksaves anywhere, with one recording across them.

Shooter

A wave shooter whose bodies are Godot's physics

Survive the waves with a hitscan rifle, an incendiary pistol, a lance that pierces, a grenade that bounces and a shot charged as it is held, behind a shield that refills. Godot's 2D physics moves every body and flies every shot; Ledger decides what each one does when it lands.

The engine owns the bodies, the world owns the rules: health, the shield, ammo, reloads, cooldowns, burns and the item's procs are content, and the places come from Godot each tick.
A raycast and a flight in one language: the rifle names what Godot's raycast found, the pistol's rounds fly as bodies, and the item's missile homes on the foe a round hit.
Foes that read the space: a grunt bites when the player is in reach, a gunner's globs can be reflected, a bearer's shield stops what meets it from the front.

In the editor

Ledger's addon puts the kernel's tools in Godot's editor: content files highlighted and completed, and a dock whose tabs say what the command line says, each line a button to the content that made it. Here it is on the ARPG.

Godot's script editor opened at the Burning effect in the ARPG's arena.ledger, highlighted, with Ledger's dock below on its Check tab: the catalog checked with no errors, and a search for Burning showing where it is defined and the four lines that name it. — Every save checks the catalog: its files, its errors and its hash. The forms and the names the content declares are searchable; pick one to open its definition and list every line that names it.

The ARPG's damage.ledger open, with the dock's Pipeline tab below: a Fire 30 hit on a fresh Hero meeting the resistance rule and landing 30, Health 300 to 270, then the pool's 16 rules in order, each naming its line. — A pool's pipeline: every rule a change to it meets, in order. A test hit, Fire 30 on a fresh Hero, shows each rule that met it and what it left, as `ledger pipeline --hit` prints it.

The ARPG's fireball.play, with the dock's Play tab: one play of 19 steps and none failing, and the play's journal beside it, each step's events. — A play file run in the editor as `ledger play` runs it, each failure a button to its line, and one play's journal, step by step.

The rest, by what each shows
