in "empire earth ii", each civilization belongs to a particular world region, each having its own regional powers. these can be activated on the game interface by clicking on a crown in the top right corner. all of the regional powers are timed; once the time is up to use it, it takes a long time for the regional powers to be recharged to use again. each regional power can only be used in a respective group of epochs. for example, the regional power of overtime can only be used by a player using a far eastern civilization in epochs 11-15.
