"Technology", or "Tech", is a common term in strategy games such as Imperialism, referring to advances in knowledge that open up new or better ways of doing things. In games where most advances depend on the discovery of other advances, a "technology tree" is a useful guide. In Imperialism, most technological advances have no prerequisites, but there is much more dependency in Imperialism 2 and some in the various scenarios of Trade Empires.
