Honestly I think that might be okay. As DA has pointed out getting around is going to be a problem for IC reasons for one thing. Hopefully the idea would be that the plotting of the players would bring people together, such as if a giant robot war machine sets France on fire people are going to want to get involved. Or flee! Whatever.

I was thinking of having a network type thing that only works for the other worldly types, but that's it. Perhaps something they use unwillingly, like they can't fully escape it even if they go live on a mountain.
