Morning!
Well, it's twofold, and I am going to keep this real - those were not the most sophisticated of games:
First, I ran a short campaign there for two years, between 2009 and 2011, while my regular group was on semi-hiatus. I honestly don't recall if AiF gives more content than just the map, and, I think, the description of a tower. - Us, we played my trademark low-fi vanilla fantasy D&D, fought against a Gorgon, and then built a scenario around a JG adventure about a halfling magic book. ("The Book of Ancestry"?) I didn't keep any notes, though, and the only thing of note I really recall is that my players feared me playing the Gorgon, because apparently, I gave them a fair beating.
Second, AiF's basic setting is obviously the main inspiration for the "Cold River Riding", from my "World of Meleon". My group and I played a campaign there from... 2013? ...Until last summer. Here's some info, though I think Photobucket has eaten all the maps by now:

The BBEG of my setting is an entity called "The Troll King", but that one is not a response to Funk, or any other existing Blackmoor character.
(FWIW, right now, I am running a Thieves' World campaign; homebrew games are fine, but I see the advantage with published settings as well, given that the background info is accessible to everyone that way. - More than anything else, I hope it will allow me to switch to a player role, instead of having to DM just all the time. So far, it works out well, but... I miss "home".)
