Nothing similar from me. But the content in Fabulous is free for anyone to use in a KF project so if someone wants to go ahead and make a very similar Fable with another layout, be my guest. It's quite easy actually. Here's a quick "how to" and you'll honestly be surprised at how well (and FAST) it will work out for you, should you chose to make such a map:
Make a hilly landscape.
Paint reasonably broad ways onto it.
Dig them in a little bit. And pull the places between the ways up some more.
Now place fences and walls on the sides of the ways. The models all come with the map! Just use fences for a couple of meters, then switch to walls, then to the other walls, then back to fences etc. pp.
Then place trees, rocks and bushes in the places between the ways and place the ruined-pillar-pieces somewhere to add some scenery.
Done. Fable landscape.
You might want to put Fable-inspired buildings somewhere to drive the point home that it's a Fable map (I have the Oakvale house, the bridge, the ruined pillars and the windmill. You can either use those or come up with your own), but it shouldn't be too hard to do.
Really easy and really fast, once you crack the style, i.e. once you know what to do. Now you do. Good luck!
(if you use anything from the map, please give me credit and maybe drop me a line. Other than that, go ahead. Please. I'd be awesome)
KF-Secure may get a playable version soon though. Some time in the coming weeks, I think. I may post new screenshots sooner. The name will be changed to KF-Atlas when the playable version is released.
