Wonders, Multiplayer II Ruleset[]


Wonders are special buildings that enhance your whole civilization. In Multiplayer II, there are several kinds of Wonders:

  • Great Wonders can be built only by the first nation who makes them.
  • Small Wonders can be built once by every player.
  • Civil Wonders powerfully define early characteristics of your national culture. You can build only one Civil Wonder.
  • Tribe Wonders are cheap Small Wonders that expire early. There are no special rules for them; the name only refers to a class of wonders which are are available early, are cheap, and accelerate your nation's early progress (if used well.)

Once built, a Wonder is placed in the city that constructed it, and cannot be sold or destroyed (unless the city is destroyed or conquered). Some Wonders become obsolete by the discovery of a certain technology, and lose their effect. Here all the Wonders are listed, in alphabetical order.

Great Wonders are in bold. Civil Wonders are marked with +. Tribe Wonders are marked with
