A strange little side quest
Here is a rabbit hole for the next loading screen in Spot the Difference: Elmo: The Oregon Trail began in 1971 when three student teachers created a computer simulation to help Minnesota schoolchildren learn American history. A second detail makes the picture even better: Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. So a round of Spot the Difference: Elmo is not just a quick distraction; it is a tiny stop on a much longer learning games timeline.
