Does anyone have any tips on creating a super dense world?  Ideally I'm looking for a world with:

• Tons of historical figures (10k+)
• 1-2 Civs of each race
• Roughly balanced populations of each race (no worlds overrun with goblins)
• Lots and Lots of Necro Towers

And a nice embark with

• Tons of Steel and Candy
• In the mountains
• A short distance (1-3 days travel) from all of the above
• Bonus: On a road or tunnel or something

I've tried playing around and I can get necro towers in dead worlds, or dense worlds with no towers, but it's hard to get both.
Steel and Candy are pretty straightforward - just jack up mineral prevalence and LEVELS_ABOVE_LAYER_4.

Anyone know what to tweak to get that density?
