Religion affects the civil issues of a nation.

[Minhcity 3]

In AOH2, changes in government do not significantly impact the civil issues of a nation, so I hope that changes in religion in AOH3 will have a strong influence on the population, thereby adding more diversity and richness to the gameplay.

- Religion should be able to increase various individual stats, such as happiness, economy, military strength, population growth, technological development speed, and especially the relationships between different religions and countries sharing the same faith, based on the real characteristics of those religions (for example, Muslim countries might have higher diplomatic scores, while relationships between Buddhist countries may not be the same).

- Religion should serve as a justification for invasion (for instance, attacking under the guise of a religious crusade could increase attack stats but result in higher civilian casualties and make assimilation more difficult; conversely, a non-religious attack could be simpler, like in AOH2).

- Having multiple religions in a nation is essential for enriching the political strategy or invasion tactics of the player. 

  + A small idea regarding multiple religions is that the assimilation of each religion will affect the religious composition in a province (this can impact public order if two or more religions are in conflict, and it will also affect defense capabilities if invading forces with a religious affiliation similar to a local faith launch an attack).

I'm sorry if my English isn't very good.
