Feature Modules

Nation & Politics

• Government System: 5 configurable government types (Feudal, Republic, Constitutional Monarchy, Military Dictatorship, Trade Federation), driven by politics.yml, with extensible custom effects (speed boost, particle effects, etc.)
• Roles & Permissions: King, Chancellor, Supply Officer, Parliament Member, and more — fine-grained permission control per role
• Decree System: Enact decrees directly or via member vote; supports tax adjustments, research bonuses, and other policy types
• Tech Tree: Research point accumulation and spending; tech lines locked/unlocked by government type; protectorate tech overflow mechanic
  

Economy

• Currency & Treasury: Each nation has its own currency circulating as physical items; minting machines consume gold ingots to produce currency
• Banking: Deposit, withdraw, transfer, and exchange currencies (15% fee; exchange rate dynamically pegged to treasury reserves)
• Loans: Apply for nation loans with interest; late repayment affects credit score
• Futures Contracts: Sellers list contracts for future delivery; buyers claim goods on due date
• Stock Market: Each nation may list one stock; price dynamically tied to national power (treasury + territory + population); supports sell-order matching and dividend distribution
• Taxation: Trade tax, land tax, vassal tax, and more; adjustable via decrees
• Economic Warfare: Embargo, sanctions, inflation attack, currency manipulation
• Economic Analytics: Real-time GDP rankings, inflation rate, and credit score tracking

Diplomacy & Warfare

• Diplomacy: Ally, trade agreement, tech agreement, hostile, and neutral relation types
• Guarantee System: Stronger nations protect weaker ones; guarantor's tech effects partially overflow to the protected nation
• Standard War: Declare war, join as Soldier / Logistics / Scout, surrender, or seek peace
• Siege War: Establish outposts and supply stations in the field to capture town cores
• Flag War: Lightweight territory contest using a timer-based flag capture mechanic

Player Status

• Temperature System: Dynamically influenced by season, biome, and equipped gear

• Hydration System: Players dehydrate in arid environments

• Profession System: Main profession + sub-profession, with leveling and experience

• ActionBar HUD: Real-time display of temperature, hydration, and profession status
  

  World Systems

• Season System: 4 seasons × 3 sub-seasons = 12 sub-seasons total; affects temperature, rain, and snow probabilities

• Chunk Resource Pricing: Biome-based resource output differences; resource extraction tracking; dynamic land pricing

• Market System: Towns host physical markets where players sell items via chest shops

• Organization System: Players create cross-nation organizations with member and outpost management

Infrastructure

• Multi-Database: SQLite (default) / MySQL (HikariCP connection pool) / MongoDB
• GUI Framework: Unified graphical interface system
• Achievement System: Player milestone unlocks
• BlueMap Integration: Land price and nation markers rendered in real time on the world map
• PlaceholderAPI: 20+ placeholder variables; compatible with TAB, DeluxeMenus, and similar plugins
• Folia Support: Async scheduler automatically adapts to both Folia and Paper
