Aztecs and Incas are the only two playable civilizations.

Aztecs are now agricultural, militaristic, industrious, religious.

Incas are now agricultural, expansionist, industrious, militaristic.

Each civ now has 2 UU's which will trigger a Golden Age.

Aztecs UU's:

1) The standard Jaguar Warrior
2) The Aztec Horseman - 3/1/2 with blitz, requires horseback riding and horses.

Incas UU's:

1) The standard Chasqui Scout
2) The Incan Horseman - 2/1/3 with blitz, requires horseback riding and horses.

Additionally, each civ starts with 2 settlers and no workers.

I tried out this mod yesterday but it just booted me out--think there must be a bug here?
