The construction of the Imperial Cathedral (Occident) and the Sultan's Mosque (Orient) are the ultimate 'bosses' in terms of logistical and economic challenges. These monumental projects require vast quantities of rare and common resources, sustained over long periods. Their 'phases' involve multiple construction stages, each demanding different materials like Glass, Stone, Tools, and Oriental goods. Their 'weakness' is a poorly optimized economy and insufficient trade routes. To 'defeat' these projects, you need a highly efficient production network, robust trade routes with both Occidental and Oriental factions, and a massive surplus of gold to fund the construction. You'll need to dedicate entire islands to specific production chains to meet the demands. The 'reward' for completing these wonders is a massive boost to your city's appeal, increased population capacity, and a significant amount of prestige, marking you as a true master of Anno 1404.
