The other MMORPG I am playing right now is asheron\'s call 2. There each month they add a new quest with specific rewards, monsters,etc. and sometimes events happen about which the players have no idea untill the event happens. For example one event was that a Dominion creature captured an enemy kingdom mine. All Dominion players recieved a message that they must defend it for a period of time, the kingdom that lost the mine had to recover it and the 3rd kingdom had to try and capture the mine for itself. This is indeed a feature that can be added only when the game is mostly complited, but it will keep the game interesting.
