That's too easy. Think of a game like Civilization. Granted, it's limited what you can learn from reading the in-game Civopedia, but probably thousands of kids have more awareness and interest in the historical progression of human civilization from playing that game.

And even if it is superficial awareness, those kinds of games exercise the fantasy-making faculties that make history itself interesting to learn about, even later as an adult.

Another example. There was this flop of a game in the early 90s, called SimEarth, that I have very fond memories of. It taught me about the Gaia hypothesis and the carbon cycle and stuff. Gameplay was pretty wacky though.
