I must confess I am a bit of a world gen junkie myself, and I have been using the legends viewer to really dig deep into the worlds I am creating and have enjoyed some minor luck with getting some of the things I want, but have failed to successfully make a truly dark, war torn world yet.
I also have a preference for dark evil worlds but I like my evil worlds filled with more monsters and titans and goblins than the clouds and rains. 900 of each of those sounds like something that would drive me nuts. I also love to have the world dominated by wars, and the majority of beings to be goblins and kobolds. Any advice about getting this would be greatly appreciated. I know there are a few mods out there that can help with this a little but I prefer to push the vanilla program to its limits than modify it.
I have been trying somethings like this:

I would love a world with more dragons, and goblins arriving on lots of scary mounts. Elves, humans etc and fine. I did see some things a world gen cook book thread somewhere about how it might be accomplished but I couldn't replicate it.
