Civilization II: Multiplayer Gold Edition was bundled both prior expansion packs and added options for networked and hotseat play, and features tweaked AI. All of the music tracks that were in the original release of Civilization II had been removed, however - only some of the "new" ones remained. The tweaked AI is also perpetually unfriendly, rendering most diplomatic functions useless. The Multiplayer Gold Edition was included in the Civilization Chronicles box set released in 2006.
