Tonlo's Religion Gameplay Extended for Humankind is a comprehensive mod designed to enhance the religious system within the game, addressing several limitations present in the original format. This expansion introduces 16 new Tenets and rebalances existing ones, providing each historical religion with unique bonuses and exclusive constructs. Additionally, players will find five new generic Religious districts and four new Religious Infrastructures, which aim to diversify gameplay strategies and strengthen underutilized districts.

The mod also introduces a new Technology in the Early Modern Era and tweaks the stability mechanics to accommodate new bonuses. With a focus on buffing weaker aspects of religion, the mod seeks to create a more engaging experience without overpowering religious builds. The adjustments made to Religious Civics and Tradition Axis bonuses are intended to offer players more strategic flexibility, making various playstyles more viable in the game.
