Mechanically it can be a little annoying with all the greydwarfs but i love the black forest. Obviously not so much for the challenge, considering you can pretty much own the black forest even before beating deer jesus (at least in the sense of surviving all the hazards with ease, maybe not in the ability to actually benefit from the available resources, unless you want to kite a troll for an extended period of time I suppose). I've always loved dense woodlands though and it kind of reminds me of when I lived back in Oregon as far as how it looks. Plus the black forest has a few fond memories for me from when i first picked up the game, mostly the majority of those "oh, that was a bad idea...very bad idea" hard lessons that come with first picking up the game (though I had a couple more in swamp to, but learned by then to just never expect anything to go right, ever. At least then the worst you get is pleasantly surprised).
