Initially I thought Arqade (f. Gaming) would be the place, but it seems that they've decided to narrow down the scope, and anything that is not "a real-world problem that you face, requiring a solution" is off-topic.
Doesn't seem to be match for GameDev either, as it isn't really about developing a game.
So is there any SE site that a question about history of video games and gaming would be on-topic?
Example of such a question: https://gaming.stackexchange.com/questions/11205/which-was-the-first-game-with-bullet-time
Another example as requested by Night Demonbobby, a question I would have asked (actually found answer on Kotaku in the mean time):
Title: What is the origin of head-shot damage multiplier?
Which game introduced head-shot damage multiplier and what was the original rationale behind it?
