NationStates
Players are able to create and manage regions, which are communities for players. Each region has a Regional Message Board, which acts as a type of forum. Each region is managed by its founder (the player who created the region), but players within the region can also choose a World Assembly Delegate. The World Assembly (WA) is an organisation and part of the game acting as a stand in for the United Nations. It makes laws that apply to nations that have joined the WA but nations are not required to be a member. It used to be called "The United Nations", however Max Barry was sent an email by the United Nations telling him to not use their trademark in his game.
