No, I haven’t run a campaign or been in a campaign taking place in Eberron. I might one day run a campaign in Eberron, but I would not base it in Khorvaire as outside of the mournlands I find it to be the least interesting continent (which is ironic as it is also the one most focused on it seems).
However I do mine some of Eberron books and lore for my own setting. My continent of Thaczil in particular is inspired by Argonnessen and information from the ‘Dragons of Eberron’ book from 3.5.
like greyhawk I voted false but we have canalized a lot for homebrew settings... We had 2 'almost' game in it though, I ran a session 0 that then fell apart before game 1 for a city of sharn 'leverage' style game, and my 1st attempt at pathfinder was kind of in eberon we used the maps and the names on the maps but the DM made up his own gods and there were no warforged
