Upon its original release, Total Annihilation Kingdoms got many complaints about balancing issues. Significant changes were made over time, based on feedback from players. Some of these changes happened quite rapidly. The final result were two balanced types of game play, for two different types of players. The regular one, and the Crusades balance. The only difference between the two is that Crusades balance prevents tier one rushes by having defensive structures do far more damage to them, and some units now have special bonuses against other units.
