Could not find this on here, sorry if it is. As a specific example, this question about the earliest game with a major escort component.
OP even doubts if it fits here, however, the question seems to have a well defined scope and the potential answers, though they might be less specific than some others, could be expected to be also fairly well defined and precise.
I can see how 'major' is up for interpretation, but 'earliest' surely isn't.
As questions go, I myself like these kind of questions, as they give me some knowledge about how gaming as a whole evolved, or some unexpected insight on the evolution or conception of a certain game mechanic.
