Everyone should show up together as a giant, sea-borne mongol-horde with max-recruited units. If they can't get a toehold with that kind of start, then it's their own fault.
I don't mind Tom's original idea of making it a realm-by-realm thing, I just think it would be awesome if 150 characters all showed up at once as one army and just started crushing realms left and right until they ran out of steam and started fighting each other.
