A common strategy in Civilization II is rushing the discovery of Invention. Leonardo's Workshop is arguably the most valuable wonder in the game. Because Invention is the prerequisite for this wonder, rushing to get this technology gives players a head start in the race to build Leonardo's Workshop.
The contrivance of a previously unknown device, method, or process which can, in turn, be used to accomplish an objective in a ways thought to be impossible, is known as invention. Essentially, inventiveness is the ability to take one or more newly discovered concepts and find a way to put them to practical use. The earliest inventions of manking date back to ancient stone and metal tools used for hunting, digging, and other everyday tasks. After writing allowed the ideas of various civilizations to be exchanged and studied, mankind's inventions became increasingly more useful and innovative. Most inventions are geared toward improving or simplifying human existence in some way. Often, inventions themselves make it possible to make new discoveries, which then go on to inspire better and more innovative inventions.
