Recently, I was surprised to learn that there was a Three Mile Island video game, by Muse Software.
Three Mile Island, for the Apple II, was published in 1979 and it was followed a year later by Three Mile Island: Special Edition, all according to Wikipedia.
And, yes, the point of the game is to avert a nuclear meltdown. What fun!
I found out the game existed through an eBay listing. Apparently they sell (or are at least listed for) a pretty penny. Here's another listing, one of about a half-dozen total. The listings range from $100 to $300, though I don't see any that have actually sold recently. I guess you'd need a working Apple computer, too, with a 5¼-inch floppy drive, to play it. (And this is also assuming that the data on a 45-year-old floppy disk is still intact, which is not a great bet.)
According to MobyGames: "This simulation puts the player at the controls of a nuclear power plant, with the challenge of operating the pressurized reactor, keeping it afloat financially, and adhering to safety procedures to prevent such disasters. The plant's operations are managed in (accelerated) real time, aided by graphical and textual information screens: detailed, animated views are available for the containment building, the turbine/filter/condenser section, the reactor core with its control rods, and the pump house. Individual subsystems like valves, turbines, pumps, rods and filters can be adjusted as needed, and the effects are visible on the various graphical displays and readout panels. ... The player will have to meet electricity demands, raise profits, handle equipment failure, and deal with government officials and their requests for inspection."
All of that sounds like an actual job! When you could have instead been playing Mystery House or Mystery Fun House.
The My Abandonware page for Three Mile Island has 15 screenshots, including a page that, ominously, just states "EMERGENCY NOTICE NO. 6, MELT-DOWN." There are also some first-person memories of the game on that webpage, which is great for the historical record. In 2019, James wrote: "I remember in 1982 was the first time I played the game. My high school in Pekin ILL had a computer room with like 20 computers. I would always get their before class and had like an hour to play. At first I would always have a meltdown before I had to leave but over time I mastered the game and could run the plant forever without melting down."
