Thank you for the great thread. I got into custom world creation lately but having trouble finding the right parameters to achieve what I seek. Maybe someone is willing to help me out?
Here is what I hope for (given the standard world generation as base):
- water placement like medium region standard
- only one pole
- more humans then elves and dwarfs
- less goblins then humans (~60-80%)
- slightly less sites blocked by settlements
- higher chance for sites with joints of different biomes
- higher chance for places with adjacent different neighbors
- higher chance of running into shallow obsidian without a surface volcano or shallow magma (probably medium deep magma?)
- slightly higher chance to find places with some trees
- lower chance for deep/very deep soil
- slightly higher chance to find coal
- slightly higher chance to find multiple different kinds of ores (not necessarily more of the same kind in total)
- slightly lower chance for vampires and werebeasts
- slightly higher chance for medium sized good/evil biomes (the ones in standard world generation are often tiny)
- approximately the same chance to run into megabeasts, HFS etc.
Thanks in advance for any help!
I'm not sure what you mean for standard world generation, but here's the parameters for a medium world where I point out what parameters you need to change:

I don't really know how to influence the number of certain civilizations, especially since it is also strongly influenced by the history generation. I know goblins need evil regions, and I think dwarfs need mountains or hills, and elves need forests.
To get more sites with joints of different biomes you just need smaller biomes, which you can achieve by turning up the variance of the terrain parameters. Turning off rain shadows might also help. This might also help in getting more sites with different neighbors, but again, I'm not sure.
For the trees, you could increase the minimum value for rainfall. Setting it to 10 will guarantee that no deserts or badlands are formed. Or you could use the weighted ranges to make low rainfall areas less likely, e.g. 5:1:2:2:2:2.
As for the rest I don't really know how to achieve it.
