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 cheap, available early, and accelerate the rise of your nation (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.
