Sid Meier's Civilization II is a turn-based strategy video game designed by Brian Reynolds, Douglas Caspian-Kaufman and Jeff Briggs. Although it is a sequel to Sid Meier's Civilization, neither Sid Meier nor Bruce Shelley was involved in its development.
There were two expansion packs that slowly added more features to the game. The first, Conflicts in Civilization, included 20 new scenarios: 12 created by the makers of the game, and 8 "Best of the Net" by fans. It also added an enhanced macro language for scenario scripting, though contained a patch that turned off the original Encarta-style Civilopedia.
The second expansion was Civ II: Fantastic Worlds (a legal dispute arising from Sid Meier's departure prevented the use of the full word "Civilization"). It also added new scenarios that had many unique settings such as one scenario dealing with colonization of Mars, one scenario called Midgard that had Elven, Goblin, Merman, and other civilizations from fantasy. There were also some scenarios based on other Microprose games such as X-Com, Master of Orion, and Master of Magic "Jr." scenarios. Fantastic Worlds also contained a new scenario editor that allowed various units, city improvements, terrain, technology trees, placing triggers, and other additions that enhanced the game.
The original game was re-released in 1997 as Civilization II: Multiplayer Gold Edition, which bundled both prior expansion packs and added options for networked and hotseat play, and features tweaked AI. However, all of the music tracks that were in the original release of Civilization II have been removed - only some of the "new" ones remain. The tweaked AI is also perpetually unfriendly, rendering most diplomatic functions useless.
Civilization II: Test of Time, a remake, was released in 1999 in response to Sid Meier's Alpha Centauri. Test of Time had a new palette and UI, and new features such as animated units, a playable Alpha Centauri to settle, and new campaign modes.
