Ok I think I found another good world with High minerals on it.
There was a Dwarf that killed a Hydra in year SIX, so I have high hopes of this!
Sadly not found another "Valley of Dwarves" like the last one, but some spots do look good.
Found a 30+ tall Volcano right on the border of a Sinister region that has raining Putrid Sludge, and a beefy River with Alligators and CARP.
Unfortunately won't be able to post screencaps till I get home from work in a few hours.
In the mean time I WILL Post the world gen for others who want to look for good spots.
Created in DF v0.34.06.

EDIT: For those following, the current plan goes as follows.
FIRST we find a spot for the fortress. Preferably near one of the Dwarf starting civs.
Once we have the spot we goto Adventure mod. The "mission" will basically be, where ever you start in the world, you will fight your way as near as possible to our fort spot and Retire.
once all Seven players have made it, we will start the fort proper.
Right now need about 5 more people to sign up as adventurers.
