Province Upgrades

Players choose one of three upgrade paths for each controlled province:

Technology (balanced bonuses) Military (defense/attack boosts) Mining (resource extraction boosts)

Upgrades unlock after holding a province for set periods (e.g., 7, 14, 30 days).

Upgrades provide scaling benefits (e.g., Mining Level 1: +10% resource yield; Military Level 2: +20% defense).

Players can only pursue one path per province, adding strategic depth.
