The Oregon Trail Game: Why We Keep Dying of Dysentery Fifty Years Later

The Oregon Trail Game: Why We Keep Dying of Dysentery Fifty Years Later

You’re staring at a glowing green screen. Your oxen are exhausted. Your wagon tongue just snapped for the third time since Fort Laramie, and now, the crushing blow: "Jedediah has died of dysentery." It’s a rite of passage. If you grew up in a certain era of the American school system, those pixelated words were your first introduction to the brutal reality of 19th-century westward expansion. But the original Oregon Trail game wasn't just some clever piece of software designed to keep kids quiet in the computer lab. It was a groundbreaking experiment in simulation that somehow became a cultural touchstone.

Most people think of the 1985 Apple II version—the one with the iconic hunting mini-game and the little white wagons. That’s the "classic" in most minds. But the story actually starts much earlier, in a tiny basement in Minneapolis in 1971. Don Rawitsch, Bill Heinemann, and Paul Dillenberger were student teachers who wanted a better way to teach history. They didn't have graphics. They didn't have mice. They had a teletype machine and a dream of making kids actually care about the 2,170-mile journey from Independence, Missouri, to the Willamette Valley.

The 1971 Teletype Beginnings

Honestly, it’s wild to think about how the first version worked. There was no screen. You typed your commands on a keyboard, and the machine spat out paper with the results. You had to type words like "BANG" to hunt. If you typed it fast enough, you got meat. If you were slow, you starved. Rawitsch spent his nights at the Minnesota Educational Computing Consortium (MECC) manually entering historical data from real pioneers' diaries to make the odds of survival realistic. He wasn't guessing. He was looking at actual mortality rates from the 1840s.

When the two-week history unit ended, Rawitsch actually deleted the program code from the mainframe. It almost vanished forever. Thankfully, he kept a printed copy of the source code. A few years later, when MECC was formed to bring computers to all Minnesota schools, he spent a weekend re-typing that code back into the system. That’s the only reason we’re still talking about it today. Without that one weekend of tedious data entry, the original Oregon Trail game would be a lost footnote in a pedagogical journal somewhere.

What Most People Get Wrong About the Original Oregon Trail Game

A lot of people remember the game as a fun hunting simulator where you just blast bears and buffalo. But if you actually play it with the intent to win, you realize it’s a brutal resource management nightmare. It's basically an accounting sim disguised as an adventure. You have a limited budget. You have to balance the weight of your wagon against the necessity of spare parts.

Buying too much food early on is a rookie mistake. Why? Because you can hunt for food, but you can’t hunt for a spare wagon axle. If you’re stuck in the middle of the desert without a spare part, you're done. Game over. You also have to consider the "pace." Setting a "grueling" pace might get you to Oregon before the winter snows hit the mountains, but it’ll kill your party from exhaustion. It’s a constant trade-off.

The Hidden Math of Survival

The game uses a series of randomized rolls influenced by your choices. It’s not just "random" bad luck. If you choose to be a banker from Boston, you start with more money ($1,600 in the 1985 version), which makes the game a breeze. If you choose to be a farmer from Illinois, you have less cash but earn more points at the end. Being a carpenter is the middle ground. Most kids just picked the banker because they wanted the fancy wagon, but the real challenge—the way the designers intended—was playing as the farmer.

The probability of contracting a disease like cholera or typhoid was tied directly to the terrain and the "health" rating of your party. If you were low on food or resting poorly, the game's internal math shifted. Suddenly, that "random" event of a broken leg wasn't so random. It was the game punishing you for poor management.

The 1985 Apple II Renaissance

While the 1971 version was the "true" original, the 1985 MECC release is what defined the aesthetic. This is where we got the hunting. You used the arrow keys to aim a little crosshair at deer, elk, and bears. It was incredibly satisfying, even if it was technically a bit broken. You could shoot 2,000 pounds of meat, but the game would dryly inform you that you could only carry 200 pounds back to the wagon.

It was a lesson in futility.

It also introduced the river crossings. This was arguably the most stressful part of the entire experience. Should you ford the river? Should you caulk the wagon and float it? Or should you pay the Indian guide or the ferry operator? Fording a river that’s more than 2.5 feet deep is a recipe for disaster. I’ve seen countless wagons sink because someone was too cheap to spend five dollars on a ferry.

Why the Graphics Mattered

The 1985 version used a limited palette. The sky was often black because of technical limitations, giving the whole journey an eerie, desolate feeling. The tombstones were perhaps the most impactful part. The game allowed you to write your own epitaphs. Because the game was played on shared school computers, you’d often come across a tombstone left by a kid in the previous class.

"Here lies Poopy Head. He died of being a loser."

It was the first social media. You were interacting with a persistent world. Seeing a friend’s name on a grave in the middle of the "Snake River Plain" section of the game made the stakes feel strangely personal.

The Reality of the Trail vs. The Game

MECC wanted accuracy, but they had to sanitize some things for a 5th-grade audience. The real Oregon Trail was much grittier. For instance, the game doesn't really touch on the environmental devastation caused by the pioneers. Millions of buffalo were slaughtered, and the trail itself was often littered with literal tons of discarded furniture, dead draft animals, and human waste.

The game also simplifies the relationship between the pioneers and Indigenous peoples. In the original Oregon Trail game, Native Americans are often portrayed as helpful guides or traders. In reality, while there was plenty of trade, there was also significant tension and violence, much of it spurred by the pioneers trespassing on tribal lands and depleting local resources.

  • Disease: Dysentery was real, but so was accidental gunshot wounds. People were bored and carrying rifles; things happened.
  • Weather: The game’s "thunderstorms" are nothing compared to the 1840s hailstorms that could kill oxen on the spot.
  • Food: You didn't just eat "food." You ate "hardtack," which was essentially a cracker so hard it could break your teeth.

Technical Limitations as a Feature

The developers didn't have much memory to work with. The Apple II version had to fit on a 5.25-inch floppy disk. This meant every line of dialogue and every sprite had to be tiny. This limitation actually helped the game's longevity. By not being overly detailed, it allowed the player’s imagination to fill in the gaps. When the game told you it was "heavy fog," you believed it, even if the screen just looked slightly different.

Why We Still Play It

There is something deeply human about the "against all odds" narrative. We love survival stories. The original Oregon Trail game tapped into that primitive urge to conquer a frontier. It’s also one of the few games where losing is actually part of the fun. Dying in a bizarre way is more memorable than reaching Oregon with a full wagon.

Today, you can play emulated versions of the 1971 and 1985 builds online. There’s even a modern "handheld" version you can buy at Target that looks like a tiny gray computer. The game has been parodied in South Park, turned into a card game, and even inspired "zombie" versions like Organ Trail. But the original remains the gold standard for educational software. It taught us about geography, sure, but it also taught us that life is unfair and sometimes you die just because the water was bad.


How to Actually Win the Original Version

If you want to revisit the 1985 classic and actually make it to the Willamette Valley without losing half your family, stop playing like an 8-year-old. Follow these steps:

  1. Pick the Carpenter: The Banker is too easy (no points), and the Farmer is a death wish for beginners. The Carpenter gives you a score bonus and enough starting cash ($800) to buy what you need.
  2. Buy Sparingly: You need 6 oxen. No more, no less. Buy 20 boxes of bullets. Don’t buy 99 sets of clothes; you only need two per person. Focus your money on spare parts (axles, wheels, tongues).
  3. The "Strenuous" Pace: Only use "Grueling" if you are trying to outrun a winter storm. Keep it at "Strenuous" and "Filling" rations. If people get sick, stop and rest for 3 days immediately.
  4. Trade Constantly: Check the "Trade" option at every fort. Sometimes you can swap a spare tire for a massive amount of food, saving you the time of hunting.
  5. Don't Ford the River: Seriously. If the water is over 2 feet, don't do it. Pay the tolls. It’s better to lose $5 than to lose your father and all your ammunition.

You can find the original 1985 version available to play for free on the Internet Archive. It runs right in your browser. If you want to see where it all began, look for the 1971 Teletype version emulators, though be warned: it’s a lot of text and a lot of "BANG" typing. For a modern take that keeps the spirit alive, the 2022 Apple Arcade/PC remake is surprisingly faithful while adding more historical nuance regarding Indigenous perspectives. Start a new trek today and see if you can beat the 1840s mortality rates.
