I suspect millions of people from my generation probably have comparable stories to tell: if not of sports simulations then of Dungeons & Dragons, or the geopolitical strategy of games like Diplomacy, a kind of chess superimposed onto actual history.

As much as we sometimes roll our eyes at the ivory-tower isolation of universities, they continue to serve as remarkable engines of innovation.

Calculus, the electrical battery, the telephone, the steam engine, the radio - all these groundbreaking innovations were hit upon by multiple inventors working in parallel with no knowledge of one another.

What you end up seeing when you look at history is that people who have been good at pushing the boundaries of possibility, and exploring those frontiers of good ideas and innovations, have rarely done it in moments of great inspiration. They don't just have a brilliant breakthrough idea out of nowhere and leap ahead of everyone else.
