Whenever the first Civilization was released. Flat out, the original Civ was never topped for me. More games have refined the idea, and executed better, but as far as a jump where I go: "I found the best game EVER", nothing matched it. The original Civ had me imagining there was FAR more to it than any other games have done. Oh, I got addicted to game stuff, but never the seeing far more in there.
MAYBE if someone were to an update of Emperor of the Fading Suns, with a better interface and so on, that might do it. But I don't see it happening personally. More on EFS:

Middle Ages meet spaces, with conquest AND politics.
