Well, i suggested somewhere already, 1 city realms. Realm cant have anything else than 1 city. Every city would be indipendent "realm" with council, with its own RC's etc.
I bet it will lead to some big alliances and federations... but still, there would be so much variables to keep huge alliances/federations stick together... its not exactly what you asked for, but i think it could lead to much more dynamic warfare and gaming. To dominate continent, you would need helluwa lot trusted buddies and pray hard that they stay that way. Realm destruction is possible, but there would be new realm at some point anyway...
Mayby test it on one of the islands... mayby test it on the island you plan to "sink" before sinking it.
