Suunman, that is exactly what it would do. That way you could make resources super rare (for all players, human and AI) or super abundant and likewise with monsters, quests, special locations.
I'd actually use special locations at that point b/c my map would look like a Christmas tree b/c I'd set it to rare. As it is now, I turn off quests/locations b/c they are in such ludicrous amounts.
Would love to see this future.
