The AI in Anno 1404 can be exploited for your benefit. Observe their trading patterns: they often have surpluses of certain goods and shortages of others. You can buy cheap from them and sell high to others, or even to the same AI if their needs change. Use gifts to improve relations with AI players you want to trade with or ally against a common foe. Conversely, you can subtly sabotage rivals by buying up all the raw materials they need, driving up prices, or blocking their expansion. Pay attention to their quests; fulfilling them can grant significant reputation boosts. If you're struggling with pirates, sometimes paying tribute to Hassan ben Sahid can buy you time to build up your navy. Diplomacy is a powerful tool; use it to secure peace, gain resources, and isolate your competitors without resorting to costly warfare.
