Well me and my IRL friend had this idea to make a roleplaying world like that small Island that was made during the Flood on Valikorlia.
For the people who never play Val this were the basics (If I recall correctly):
Everyone would be able to do what they could with the items they brought from the flood and the people they grouped up with.
The staff was basically working on the players whims as long as it would be RP logical. On Val it was (IMHO) quite corrupt because of the staff members who only approved their idea's.
Well anyway.
My (Or me and my friend's) server would be like that but then much bigger and with 3 NPC nations to make a solid base. 2 "good" nations and one "evil"
Along with lots of different races this would mean total freedom for the player to actually play a RP land where they CAN make a difference instead of playing in a world where only the BIG events can make a difference.
It requires a huge overworld i know that but in the end i think it will be awesome to do.
