Gonçalo delivered a comprehensive gameplay expansion for the EoaNB-Team/EoaNB repository, focusing on a full overhaul of Switzerland’s national focus tree and the introduction of a new industrial focus tree. Using Paradox Script and txt, Gonçalo restructured political and economic decision paths while refining historical data for manpower, cultural, and religious distributions to enhance realism and balance. The work emphasized data-driven improvements and modular design, broadening economic development options and resource management mechanics. No major bugs were reported or fixed, reflecting a focus on feature depth and stability. The project demonstrated strong skills in game development, modding, and focus tree design.
