The Suggestion Box has returned to no longer requiring topics to be approved by moderation before they can be commented on.
Bear in mind that the standard forum rules still apply to submitting and commenting on suggestions. Any suggestions which do not adequately explain the ideas being proposed, advertise other games, degrade into a flame war, are excessively repeated, and so forth will be subject to locking or removal at the discretion of the moderation staff.
As an example say I wished to propose the addition of cities which each nation could create. The role of my suggestion thread would be to explain how this featured would work if it were added to Cyber Nations. Discussing how other games utilize this mechanic is irrelevant to justify my idea since I am trying to make a case for why and how it should be added here.
