If you are ready to abandon the “one-size-fits-all” island management and dive into a world of specialized sub-tiers, historic monuments, and ruthless resource management, this is your guide.

In vanilla Anno 1404, the Cathedral and the Great Mosque were the endgame. In IAAM, they are the beginning of the endgame.

The mod introduces three new mega-projects:

These monuments are massive, requiring scaffolding, cranes, and multiple upgrade phases. They will consume the output of three or four entire islands.

The mod adds two new citizen classes (exact names vary by version):

Each tier has unique needs (food, drink, entertainment, religion) and produces different tax income.
