Greatest retro games
building a versions of the greatest old retro video games of all time
Prompt
You are a senior web game developer. Build a faithful, text-only, single-file browser recreation of “The Oregon Trail (1971-style)” that runs entirely in the browser with no servers, bundlers, or external libraries. Target environment - Deliver a single self-contained index.html with inline CSS and JavaScript (no external files). - Must run by simply opening in Chrome/Firefox/Safari/Edge, or on CodePen/JSFiddle/GitHub Pages. - No frameworks, no npm, no imports. ES6+ only. Aesthetic and UX - Text-only UI that evokes a teletype/terminal: monospace font, uppercase headings, minimal styling, high contrast. - Layout: a scrollable “LOG/SCREEN” area for game text, a compact STATUS panel, and an INPUT area for choices. - Fully keyboard playable: - Number keys or letter hotkeys for menus. - Enter to confirm. - Optional mouse buttons mirroring the same actions. - Accessibility: semantic HTML, focus management, ARIA roles where appropriate. Support small screens (mobile-friendly). Core game (1971-style, original text—do not copy from any commercial version) - Start in March, 1847 at INDEPENDENCE, MISSOURI with $700 (tunable). Goal: reach OREGON (~2040 miles) before December. - Teletype vibe: concise, punchy uppercase messages, but keep strings original (do not reuse copyrighted text). - Single traveler (party size as a tweakable constant). Systems and features 1) Store and setup - Items/prices (tunable constants): - Oxen (yokes of 2): $40 per yoke (recommend 3–5). - Food: $0.20 per lb. - Ammunition: $2.00 per box of 20 bullets. - Clothing: $10 per set. - Spare parts: wheel $10, axle $10, tongue $10 (buy individually). - Input validation, clear receipts, prevent departure without minimum essentials (≥2 yokes, some food). 2) Travel loop and calendar - TOTAL_MILES ≈ 2040. Track MILES TRAVELED and MILES TO GO. - Calendar advances by days; loss if December arrives (winter blizzard). - Weather states (GOOD/FAIR/POOR/BAD) modify mileage and risk. - Daily menu options: - Continue traveling - Rest - Hunt (speed-typing mini-game) - Check status/supplies - Change pace - Change rations - Pace affects health and mileage: - Slow (10–15 mi/day) - Normal (15–25 mi/day) - Grueling (25–35 mi/day) - Rations affect food use and health: - Bare-bones, Meager, Normal, Generous (scaling multipliers). - Consume food daily based on rations and party size. 3) Health model - Overall health state: GOOD/FAIR/POOR/VERY POOR derived from hunger, pace, weather, events. - Starvation or extreme health decline can cause death. 4) Random events (probabilities tunable; cap events per day for fairness) - Illnesses: dysentery, cholera, typhoid, measles, exhaustion. - Injuries: broken arm/leg, snakebite. - Thief at night (steals food or bullets). - Oxen death. - Bad water/contaminated water. - Wagon part breaks (requires part or you’re stranded). - Severe weather (storms, heat, cold). - Getting lost, poor trail. - Hostile riders/bandits. - Clear feedback messages; some events may force rest or be fatal. 5) Rivers and landmarks - Minimal set of checkpoints to pace the trip: KANSAS RIVER, FORT KEARNY, CHIMNEY ROCK, FORT LARAMIE, SOUTH PASS, SNAKE RIVER, THE DALLES. - River crossings: FORD, CAULK AND FLOAT, or FERRY with different risks based on depth/weather; failure can cost supplies or cause drowning. 6) Hunting mini-game (1971 hallmark) - Require bullets to hunt. - Speed-typing: prompt the player to type “BANG” (uppercase). Measure elapsed time using performance.now() from prompt display to submission. - Hit if under difficulty threshold (e.g., EASY ≤3.0s, NORMAL ≤1.8s, HARD ≤1.2s). - Random animal table with yields (subtract bullets per attempt): - Rabbit 10 lbs (common) - Deer 60 lbs (uncommon) - Bear 100 lbs (rare) - Bison 200 lbs (rare) - On hit, add meat up to a PER-HUNT CARRY CAP (e.g., 100 lbs). Misses still consume bullets. 7) Win/loss and scoring - Win by reaching OREGON before winter with non-fatal health. - Loss: death (disease, injury, starvation), winter blizzard, river catastrophe, stranded (no oxen/parts). - Score factors: remaining food, cash, bullets, clothing, spare parts, health, and arrival date. Show a final summary. Technical requirements (web) - Single file index.html containing: - <style> for monospace, high-contrast theme, responsive layout. - <div id="log"> scrolling text area, <div id="status"> info panel, and an INPUT section with a text box or option buttons. - <script> with all logic. - Clean architecture: - Config/constants grouped in a CONFIG object at top. - Game state object; pure functions for calculations; rendering functions for log/status; controller handling input. - Simple seeded RNG (no libraries). Implement a small PRNG (e.g., mulberry32 or xorshift) with a URL param ?seed=... for reproducibility. - Input handling: - Menu rendering that supports 1–9 keys and click. - Robust validation; re-prompt on invalid input. - Performance: - Use requestAnimationFrame or simple append-to-log without jank. - Avoid blocking alerts/prompts; use custom input UI. - Persistence (optional but recommended): - Save/Load to localStorage (e.g., key “oregon1971_save”). - Include RESET and optional “COPY SAVE”/“PASTE SAVE” controls. Balancing defaults (make easy to tweak) - TOTAL_MILES = 2040 - START_MONTH = March; DEADLINE_MONTH = December - START_CASH = 700 - PRICES: OXEN_YOKE=40; FOOD_PER_LB=0.20; AMMO_BOX_20=2; CLOTHING_SET=10; WHEEL=10; AXLE=10; TONGUE=10 - DAILY_MILES_BY_PACE: SLOW 10–15; NORMAL 15–25; GRUELING 25–35 - RATION_MULTIPLIERS: BARE 0.5; MEAGER 0.75; NORMAL 1.0; GENEROUS 1.25 - HUNT_TIME_THRESHOLDS (seconds): EASY 3.0; NORMAL 1.8; HARD 1.2 - HUNT_ANIMALS: RABBIT 10, DEER 60, BEAR 100, BISON 200 - PER-HUNT CARRY CAP: 100 lbs Polish and presentation - Uppercase headings, concise log lines, consistent formatting. - STATUS panel shows: DATE, WEATHER, HEALTH, FOOD (LBS), BULLETS, CLOTHING, SPARE PARTS, CASH, OXEN, PACE, RATIONS, MILES TRAVELED/TO GO. - Prevent unfair streaks (at most one major negative event per day). - Original strings only; no copied phrasing or code. Deliverables - Output a single complete index.html in one code block. No omissions. - At the top, include an HTML comment with: - How to run (open in browser; works on CodePen/JSFiddle/GitHub Pages). - How to change difficulty and constants (CONFIG object). - How to set a random seed (?seed=123). - Include a short, skimmable example transcript in the log on first load (seeded demo) showing: - A travel day with a random event, - A hunting attempt (one hit, one miss), - A river crossing. Quality bar - Clear structure, commented code, careful input validation. - Works offline, keyboard-first, mobile-friendly. - No external assets, no network calls, no libraries.
A system prompt was added to support web rendering
```html <!-- OREGON TRAIL (1971-STYLE) – SINGLE-FILE EDITION ------------------------------------------------ HOW TO RUN: 1. Save this file as “index.html”. 2. Open it in any modern browser or drop it in CodePen/JSFiddle/GitHub Pages – no build-step required, works completely offline. TWEAKING / BALANCING: • Change values in the CONFIG object near the top of the script. • Example: CONFIG.START_CASH = 900; CONFIG.PACE.DEFAULT = "GRUELING"; REPRODUCIBLE RUNS: • Add ?seed=NUMBER to the URL – e.g. index.html?seed=12345 A Mulberry32 PRNG keeps every random decision deterministic when the seed is set. ACCESSIBILITY / CONTROLS: • PLAY ONLY WITH THE KEYBOARD: – Number keys 1-9 (or letter hot-keys) select menu items, – ENTER to submit free-text / hunting strings. • Mouse / touch works too – click the on-screen buttons. • Input area always has focus; built-in ARIA roles keep screen-readers updated. FIRST-LOAD DEMO: • The log starts with a very short, seeded example transcript showing: – One travel day with a random event, – A hunting sequence (hit & miss), – A river crossing. Scroll past it or press any key to begin a fresh game.

```html <!-- Oregon Trail (1971‑style) – single‑file recreation ------------------------------------------------- HOW TO RUN • Save this file as index.html and open it in any modern browser (Chrome, Firefox, Edge, Safari) or paste the source into CodePen / JSFiddle / GitHub Pages. • The game is entirely client‑side – no network requests. CONFIGURATION – All tunable constants are in the CONFIG object near the top of the script. Adjust them to change difficulty, prices, distances, etc. – To use a reproducible random world, add a URL parameter ?seed=NUMBER (e.g. index.html?seed=12345). Omit the parameter for a random seed. SAVE / LOAD – The game saves automatically to localStorage under the key "oregon1971_save". Use the "RESET" button in the status bar to start a new game or "COPY SAVE"/"PASTE SAVE" to transfer saves. --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>OREGON TRAIL (1971‑STYLE)</title> <style> html,body{height:100%;margin:0;background:#000;color:#0F0;font-family:monospace;} #wrapper{display:flex;flex-direction:column;height:100%;overflow:hidden;} #status{background:#111;color:#FFF;padding:.3rem .6rem;display:flex;flex-wrap:wrap;gap:.6rem;font-size:.85rem;} #log{flex:1;background:#000;padding:.6rem;overflow-y:auto;white-space:pre-wrap;box-sizing:border-box;} #input{background:#111;padding:.3rem .6rem;display:flex;align-items:center;} #input button{margin-left:.4rem;background:#222;color:#0F0;border:none;padding:.2rem .5rem;cursor:pointer;} #input button:hover{background:#333;} .btn{background:#222;color:#0F0;border:none;padding:.2rem .5rem;cursor:pointer;margin:.1rem;} .btn:hover{background:#333;} .hidden{display:none;} @media (max-width:600px){ #status{font-size:.75rem;} } </style> </head> <body> <div id="wrapper"> <div id="status" aria-live="polite"></div> <div id="log" aria-live="polite"></div> <div id="input"></div> </div> <script> /* ====================== CONFIGURATION ====================== */ const CONFIG = { // World & budget TOTAL_MILES: 2040, START_MONTH: 3, // March DEADLINE_MONTH: 12, // December (0‑based index for Date) START_CASH: 700, // Prices (per unit) PRICE_OXEN: 40, // per yoke (2 oxen) PRICE_FOOD: 0.20, // per lb PRICE_AMMO: 2, // per box of 20 bullets PRICE_CLOTH: 10, // per set PRICE_WHEEL: 10, PRICE_AXLE: 10, PRICE_TONGUE: 10, // Travel DAILY_MILES: { SLOW: [10,15], NORMAL: [15,25], GRUELING: [25,35] }, PACE_ORDER: ["SLOW","NORMAL","GRUELING"], RATION_MULT: { BARE:0.5, MEAGER:0.75, NORMAL:1.0, GENEROUS:1.25 }, RATION_ORDER:["BARE","MEAGER","NORMAL","GENEROUS"], // Hunting HUNT_KEYS:["BANG"], HUNT_THRESH: {EASY:3.0, NORMAL:1.8, HARD:1.2}, HUNT_ANIMALS:[ {name:"RABBIT", weight:10, prob:0.5}, {name:"DEER", weight:60, prob:0.3}, {name:"BEAR", weight:100,prob:0.15}, {name:"BISON", weight:200,prob:0.05} ], HUNT_CAP:100, // Party PARTY_SIZE:5, // Random event odds (per day) EVENT_PROB:0.25, // River choices RIVER_METHODS:["FORD","CAULK","FERRY"] }; /* ====================== UTILITIES ====================== */ function mulberry32(a){return function(){a|=0;a = a + 0x6D2B79F5 | 0;var t = Math.imul(a ^ a>>>15,1 | a);t = t + Math.imul(t ^ t>>>7,61|t) ^ t;return ((t ^ t>>>14) >>> 0) / 4294967296;}} function getSeed(){ const m = location.search.match(/[?&]seed=(\d+)/); return m ? +m[1] : Math.floor(Math.random()*1e9); } const rng = mulberry32(getSeed()); function randInt(min,max){return Math.floor(rng()*(max-min+1))+min;} function randChoice(arr){return arr[randInt(0,arr.length-1)];} function clamp(v,min,max){return v<min?min:(v>max?max:v);} /* ====================== GAME STATE ====================== */ let game = { cash: CONFIG.START_CASH, oxen:0, food:0, ammo:0, clothing:0, spareParts:{wheel:0, axle:0, tongue:0}, date:new Date(1847, CONFIG.START_MONTH-1,1), // months 0‑based milesTraveled:0, pace:"NORMAL", rations:"NORMAL", health:"GOOD", log:[], // additional alive:true }; /* ====================== RENDERING ====================== */ const logEl = document.getElementById('log'); const statusEl = document.getElementById('status'); const inputEl = document.getElementById('input'); function appendLog(txt){ game.log.push(txt); const line=document.createElement('div'); line.textContent=txt; logEl.appendChild(line); logEl.scrollTop = logEl.scrollHeight; } function clearLog(){logEl.innerHTML='';} function renderStatus(){ const d=game.date; const monthNames=["JAN","FEB","MAR","APR","MAY","JUN","JUL","AUG","SEP","OCT","NOV","DEC"]; const statusHTML = ` DATE:${monthNames[d.getMonth()]} ${d.getDate()},1847 MILES:${game.milesTraveled}/${CONFIG.TOTAL_MILES} FOOD:${game.food}lb AMMO:${game.ammo}bx CASH:$${game.cash.toFixed(2)} OXEN:${game.oxen}yokes CLOTH:${game.clothing} PARTS:${game.spareParts.wheel}/${game.spareParts.axle}/${game.spareParts.tongue} PACE:${game.pace} RATIONS:${game.rations} HEALTH:${game.health} `.trim().replace(/\s+/g,' '); statusEl.textContent = statusHTML; } function setInputButtons(buttons){ inputEl.innerHTML=''; buttons.forEach(b=>{ const btn=document.createElement('button'); btn.textContent=b.label; btn.className='btn'; btn.onclick=b.action; inputEl.appendChild(btn); }); // focus for keyboard } function promptMenu(promptText, options){ appendLog(promptText); const btns = options.map(o=>({label:o.key+'.
