Other things that could happen
- a vulcano erupts, creating a barren waste where an AI controlled abyssian empire is spawned..

- You could increase the map while leaving the original lands intact --> exploration all players (or at least parties) would have to be situated somewhat equal to map edges to make this fair

- in the same thing you could add portals to the world later (just new map connections connecting far away lands) so standing defences would be less valuable (though end game has magic to do this so probably need to do this in mid game)

- and via same options you could even unlock new worlds (just place a new map beside the current one with a few connections as done in underworld maps or multi-layer maps)
