Great Game! (Also map questions, please help)

[texAnimator]

I just recently bought Dom2 and I haven't been able to get much work done since!

Thanks for making a great game.

I'm making a map too, but i have some questions. I have the white dots and everything, seems to be working fine, but is there a way to limit the playable nations to only the ones that can handle hot provinces?

It takes place in a Lavaworld type place afterall...

Any advice(or links to advice) on what resources(mountains, etc,) are most valuable to hot nations?

Thanks,
tex
