Worked on the openfrontio/OpenFrontIO repository to deliver a comprehensive update focused on map geographical and historical accuracy. Enhanced nine maps by refining nation names, spawn positions, and flag codes, ensuring improved data accuracy and historical consistency without impacting gameplay mechanics. Utilized JSON for map data management and applied game development and map design skills to add regional coverage, such as Canadian provinces and Brazilian states, while correcting spawn positions in several South American regions. Validated all changes through editor testing, updated localization files, and included UI screenshot coverage, resulting in a release-ready, globally consistent, and internationally adaptable map dataset.
