I like the idea, but I have to warn you- it likely won't get off its feet.

I do not mean to be rude, just, well, I've tried this before, except on a much smaller scale- five cities within close proximity, rather than an entire world. The problem is that everything gets too spread out- little character interaction, unless everyone clumps. That, and you went ahead and started the roleplay without waiting for interest in your interest check. The interest check is just that- to see if anyone's interested before you actually start working for a roleplay. It's a terrible shame to get started on a roleplay, and put many a hour into it, and not have a single player join- I've felt that several times, even when people say they're interested.

This might take off better as a nation roleplay- where somebody is controlling each nation, or if it's large enough, the different fiefs within the nation.
