With the release of Dune 2, the movie, I'm naturally thinking about Dune II, the start of the strategy genre, from legendary developer Westwood. The games they made prior to that? Why, Goofy's Railway Express, of course.
This educational title is a Disney series of PC releases with the barest interaction. The box even advertises "Colours and shapes" as a feature. Kids hit the spacebar if the shape in the billowed smoke matches the landscape, which rewards them with a little animation. Also, the train's continual computational noises are deafening, as it goes back and forth over the same vistas. And then they made a dozen Command & Conquer games.
