Unofficial Expansion Project
Legends of Revolution is for civilization IV BTS
The Goal of Legends of Revolution is to simulate a "commercially viable" expansion pack. As with any good expansion pack a new base concept is introduced: Revolutions, which carries with it concepts like barbarian civs, battles effecting national borders, and civil wars. Further certain gaping holes in the unit progression of default cIV are filled; like the much needed bombard, and steam ship navies of the Industrial era are flushed out. Overall Legends of Revolution has been built with the idea that more is not better, rather the goal has been to add in needed units for balance, and concepts that enhance gameplay.
