My friend Eli runs his own gaming blog, called "I See Lead People." I've mentioned it before here, I am sure, and there's a link to the blog in my links.
Anyway, he threw out an idea sort of off-the-cuff for a new VSF power: Hawaii. Before you scoff, check out this link: http://leadpeople.blogspot.com/2009/04/atler-nations-kingdom-of-hawaii-part-1.html. It fleshes out the idea a little more, and begins to make some sort of sense. I could see the Kingdom of Hawaii becoming as powerful as, say, the Papal States, Imperial Mexico or even the Republic of Texas, with the right set of circumstances.
At any rate, its a fun idea to kick about. Check it out, and let Eli know what your thoughts are.
