From your about page, it seems to me like the monsters should become more dangerous the further you travel from civilization.
Looking at the world map, I'd guess you've currently just implemented a static/hard coded range from the center of the world to determine level of spawned creatures. Am I possibly wrong, or is there a plan to make me wrong in the future?
It'd be pretty cool if the server worked out some statistics on population & construction density and used that information to determine type and level of creatures, so that after enough time of building up our far flung settlements we could create pockets of safety with harsh wildernesses joined by roads that need regular patrols by armed player characters to keep safe from bandits and the like
