A completely rebalanced modification for SS 6.4, adding new unit pools, buildings, tweaks and two new factions - Second Bulgarian Empire and Volga Bulgaria (Kazan Khanate). Makes the game perfect for replaying, as it completely changes the population,taxation, etc numbers as well as diplomacy and many other mechanics.
The current version of "Rise of Bulgaria" re-balancing mod for SS 6.4. Greatly improved gameplay for the base SS 6.4 version.
