Would your rather have some prebuilt Role Playing Starting cities as the Capital (that fit the theme of oort) rather than, big community things that normally have no recurring themes?
in this case you could choose the best builders of oort online and put them into some of the launch worlds a few weeks early with a creative type mode so that they could build starting cities that look good.
im stating that question due to the fact most worlds i go onto the capital tends to be very ugly and has no theme sometimes its a mix between futuristic and medieval then just plain boring builds.
in these terms you could get player run shops here and make the plots expensive each month guilds bid on a plot/shop and the biggest bet on that area gets a guild store there kind of thing and permissions to build inside that area, the money from these bets would run into the economy or the upkeep of the city lets say you make it that things in beacons degrade over time if you put money into that beacon it prevents from decaying. this may or may not be good in the overall economy, depending on how you view it. obviously those who have guild stores in that area will be open for players in that guild to have a sort of auction house to sell their things (good for tradeing guilds).
Tell me and i will make a separate more detailed topic for you to look at about that idea.
