I'm in. I'll take any spot, but would prefer an earlier one. My comp has problems when it gets to be closer to 200 dorfs.
Worldgen:
* Ironhand is good with me. I've been using this one for a while, and like it.
* Extra Z-levels between caverns are good. Do we need all three cavern layers? I understand that you can go down to 2 caverns, and still get everything.
Other than that, I don't know much about world generation...
