Civilization III: Play the World is the first expansion pack for Civilization III released in October 2002. Play the World added more civilizations a new multiplayer feature new Wonders of the World new units and new game modes including: elimination regicide and capture the flag. One of the major features of Play the World was a "turnless game mode" a new concept never used in the previous versions of the Civilization series. The game mode allowed a sort of mixture between turn based and real time gameplay. Although the concept was good in theory it rarely worked as intended and many online players experienced "Out of sync" problems along with others. Little support from Firaxis and the sundry other problems resulted in the gamemode not returning in Civilization IV.
