Worked on the Rekordny/Project_IRIS repository to refine gameplay mechanics and event triggers, focusing on balancing idea modifiers, national focus availability, and event outcomes for TDL and TER nations. The approach centered on configuration and game development skills, using txt-based configuration files to introduce new historical event chains and enhance strategic depth. Adjustments were validated through targeted commits, ensuring alignment with product goals for improved balance and player engagement. The work emphasized technical precision in tuning core systems rather than broad feature expansion, contributing to long-term retention by stabilizing gameplay and enriching the experience for specific in-game nations.
