Civilization Rise & Fall — 4 Ages of Humankind (3D Saga)

## What this is A **single-file autonomous 3D Civilization-style 4-age saga**. 4 civs colonize an 8×8 hex world, build wonders, research the tech tree from Pottery to Singularity, fight wars, suffer plagues, and either ascend to Type-II Kardashev or collapse into a new dark age. 8 minutes per saga. Forever. ## Why this is mind-blowing **AGE 1 — STONE & CLASSICAL.** Sky is muted ochre. Hexes are pristine. Four civs of huts. Prof. Helena Vance (white anchor PIP, scholarly): *"This is CIV-NET. Welcome to the dawn of humankind."* Banner: *"AGE I — STONE & CLASSICAL — YEAR 0 OF HUMANKIND."* First city founded — banner: *"BLUE FOUNDS THEIR CAPITAL ON THE RIVERBANK."* Tech panel lights up: *"TECHNOLOGY UNLOCKED: POTTERY."* **AGE 3 — INDUSTRIAL.** Sky is sooty grey. Pollution tint over the hexes. Cities have skyscrapers. Doc Marsh (gold, futurist): *"The Industrial Revolution has transformed the planet — and the air with it."* Banner: *"WONDER COMPLETE: HOOVER DAM."* Tech tree: *"INDUSTRIALIZATION → COMPUTING UNLOCKED."* Then red banner: *"WORLD WAR DECLARED — RED vs PURPLE."* Cities pause growth. Battlefield cam swings to the front line. **AGE 4 — SPACE.** Sky clears. Domes rise. Spaceport built — rocket fires. *"MOON LANDING."* Then *"MARS COLONY."* Banner blooms gold: *"CIVILIZATION COMPLETE — ASCENSION TO TYPE-II KARDASHEV."* OR random 50/50: *"CIVILIZATION COLLAPSED — A NEW DARK AGE BEGINS."* 12-second civ-flag ceremony. Reseed. Year 0. Loop.

An autonomous 3D Civilization-style civ rise-and-fall saga. 4 ages: Stone/Classical → Medieval/Renaissance → Industrial → Modern/Space. 8x8 hex-tile world with 6 biomes (plains tan, forest green, mountain grey, river blue, desert yellow, tundra white). 4 civs (random colors, random names, random leader-name from 16x16x16 pool) growing cities visibly: hut → village → walled town → metropolis → space-age dome. 12 wonders modeled as 3D landmarks (Pyramids, Hanging Gardens, Great Wall, Coliseum, Cathedral, University, Bank, Industrial Park, Hoover Dam, Internet, Spaceport, Mars Colony) — when built, camera zooms to construction with banner. 12-node tech tree DOM panel: Pottery → Bronze → Iron → Currency → Mathematics → Astronomy → Gunpowder → Steam → Industrial → Computing → Spaceflight → Singularity. Each new tech unlocks city upgrade. Sky/fog/light morphs across ages: stone-age dim → industrial sooty → space-age clear. Industrial pollution tint. Random events: BARBARIAN INVASION, PLAGUE, INDUSTRIAL REVOLUTION, WORLD WAR, COLD WAR, MOON LANDING, MARS COLONY, CIVILIZATIONAL COLLAPSE (~50% chance to reset). 6 director cameras (WORLD / CITY / BATTLEFIELD / WONDER / ANCHOR / SPACE) with smooth lerp + sway. 2 narrators on canvas-anchor PIP (Prof. Helena Vance white historian / Doc Marsh gold futurist) with mouth animation. Broadcast UI: CIV-NET logo + LIVE pulse, age banner, year ticker, tech tree panel left, wonders+leader panel right, 4-civ score grid, scrolling ticker. Lower-thirds: WHO IS, TECH UNLOCKED, WONDER BUILT, AGE TRANSITION. 12s ceremony with civ-flag overlay (collapse or ascension). Full reseed and restart forever.

What I learned shipping it

Sky/fog/light morphing across 4 ages (stone-age dim → industrial sooty → space-age clear) transforms the SAME hex world into 4 visually distinct eras — viewers can tell the era at a glance without reading any UI. Costs 4 keyframes of color lerping.

12-node tech tree as DOM panel (lit / now / locked states) is the single most readable 'progress over millennia' visual — a viewer joining mid-saga instantly sees how far humanity has come and what's next, no exposition required.

50/50 collapse vs ascend ending makes a long civ saga rewatchable — viewers stick around for the second loop because they don't know if humanity will reach the stars or fall to barbarism. Deterministic endings kill the genre.
