From the mid-80s to the late 90s I ran a series of games in Greyhawk, though over time it diverged to quite an extent from "official" Greyhawk.
In the mid-80s I also ran an Oriental Adventures game, using the description of the lands in the OA book. From 1998 to 2008 I ran another Oriental Adventures game, this time using the boxed set for maps and a bit of backstory. (Much more of the play-relevant backstory came from modules and my own imagination.)
Since 2009 I've been running a 4e game, using the default cosmology and mythic history, but using the map in the old module Night's Dark Terror, supplemented by a city map from Speaker in Dreams (which is merged with the Threshold city map from NDT). On current projections, I would say that the end of that campaign has a good chance of seeing the end of that world, so no replay (unless via Dark Sun, if the world goes in the Primordial rather than the Divine direction).
Once the 4e game is done, I'm hoping to run a Burning Wheel game. My plan would be to use Greyhawk for the basics of setting for that (but BW is not big on detailed backstory prior to play, so that would be for some basics of maps and names, rather than lots of detail).
