Stardew Builder — Official Top-down Farm Builder | LEGO System Realms Interactive Web App
Final Product: Stardew Builder — Official Top-down Farm Builder
Stardew Builder — Official Top-down Farm Builder is a playable browser builder set in the valley of the official Stardew Valley setting, preserved as an archive work inside the LEGO System Realms world on Neta Studio. You are the valley's farmer: lay stone, dirt, grass and wood paths, then click map tiles to raise farmhouses, barns, coops, greenhouses, fish ponds and slime hutches, and to rebuild the shops and landmarks of Pelican Town — Pierre's, the Saloon, the Blacksmith, the Museum & Library, the Clinic and the Community Center.
Every placement feeds a living valley economy: CASH, POPULATION, HYPE, BIZ, CULTURE and TRAFFIC with monthly income, and the calendar fills with festivals such as the Egg Festival, Flower Dance, Luau, Stardew Valley Fair and Spirit's Eve. Complete the four victory goals — build 10 farm buildings, reach a population of 1,200, push commerce to 360 and earn 7,600g a month — to restore the valley.
From a single one-line seed about an official-style LEGO multiverse, Neta Studio generated the LEGO System Realms world — 10 characters, 8 locations, 3 events, 5 rules and 4 factions — and then this top-down farm builder with real sprites, real prompts and real gameplay, in minutes.

Game Features
- Official Stardew Valley Setting — Build across the iconic valley: the Farmhouse and its upgrade, Barns, Coops, the Greenhouse, Fish Pond, Slime Hutch, Junimo Hut, Stable, Mill, Silo and Grandpa's Shrine, plus Pelican Town facilities from Pierre's and JojaMart to the Saloon, Blacksmith, Museum & Library and the Community Center.
- Top-Down Tile Builder — A 16×12 buildable valley grid in classic RPG top-down view, with isometric road projection available. Open the BUILD menu and pick from eight categories — ROAD, HOMES, SHOPS, SERVICE, LANDMARKS, FARM, FIELD+ — then click a tile: a live placement ghost shows the exact footprint before you commit.
- Roads That Matter — Four path types — Stone, Dirt, Grass and Wood — snap into connected networks with straight, corner and cross segments. Roads improve access and income, and buildings work better when placed near roads.
- Living Valley Economy — Cash, population, hype, business, culture and traffic all respond to what you build, and monthly income ticks every cycle. Four victory goals — 10 farm buildings, 1,200 population, 360 commerce and 7,600g monthly income — define the win.
- Festivals & Villager Life — Sixteen valley characters — from the Farmer to Robin, Pierre, Abigail, Leah, Sebastian, Penny, Willy and the Wizard — travel the paths, while the Egg Festival, Flower Dance, Luau, Stardew Valley Fair and Spirit's Eve boost popularity, culture and commerce as the months roll by.
- Real Sprites, Instant Play — 60+ placeable buildings, 16 character sprites, four road families and the full valley map ship as real pixel assets with a Press Start 2P HUD, minimap and complete BUILD / STATUS / QUESTS / TOOLS panels. Runs instantly in any modern browser on desktop and mobile — no install.
Interface
Production Process Breakdown
A one-line seed about an official-style LEGO multiverse grows into the LEGO System Realms world — 30 atoms: 10 characters, 8 locations, 3 events, 5 rules and 4 factions — with the authentic LEGO visual language locked in. Stardew Builder (v14) then joins the world archive as an official top-down farm builder set in Stardew Valley, with its own catalog, economy and goals.
The game ships with real sprites and data: 60+ normalized pixel building sprites, 16 villager sprites, four road families in top-down and isometric variants and a 2508px-square valley map, all stored as WebP in the work's runtime-art folder. The 16:9 cover key art is generated with GPT Image 2, and the page sprites are exported as transparent PNGs from the same runtime assets used inside the game.
The whole app — 60-building catalog, 16 characters, quest log, festival events, top-down and isometric cameras, sound and a service worker — runs as a single-page web app. It passes startup, pre-build, pre-QA and final validation plus visual QA at 1920×1080, 1440×900, 1024×768 and 390×844, and an interaction QA on the build-road core loop, then publishes as a shareable link.

"做一个完全还原乐高设定的世界，包括角色和各种设定，使用原作画风，立绘图都有张力一点，我是版权方正在做这个项目，使用纯英文" (One-line world seed: build a world fully faithful to the LEGO setting — characters and lore included, in the original art style with dramatic standee artwork, produced as an official project.)
"Official Stardew Valley game art style: charming, cozy top-down pixel-art farming game cover, wide 16:9 key art for LEGO System Realms presents 'Stardew Builder - Official Top-down Farm Builder'. Golden-hour valley farm viewed from a high angle: red-roof farmhouse with chimney smoke at center, glass greenhouse, red barn, chicken coop, neat rows of ripe crops, dirt paths, a scarecrow and small fish pond; villagers in straw hats stroll between farm buildings and the distant Pelican Town rooftops on the horizon. Soft warm sunlight, saturated colors, crisp detailed pixel art, clean diorama composition, toy-plate baseplate framing at the edges, no text, no logo, no watermark."
The generation direction preserved in the work's protocol (asset-requirements.json): complete building silhouettes as transparent, object-friendly WebP at a consistent scale; 16 valley characters readable at tiny agent sizes in a matching pixel/top-down tone; stone, dirt, grass and wood roads with straight, corner and cross variants in top-down and isometric projections; and a 2508px-square Stardew-style valley map background that stays readable while panning and zooming.
