How're you working religion, then?
Sorry Virote for answering your question lately, but this is an absolute core concept of CCM:
Better implementation of religions:
At least since the mod "Rhye's of Civilization", it was shown, that different religions can be an interesting part of Civ 3. But I only knew mods, where different religions worked alternative, mostly with their own alternative techboxes.
In CCM religions work cumulative for a civ and in CCM a lot more of happiness provided by cummulative religious buildings is needed to balance a lot more of unhappiness compared to the standard Civ 3 caused by other new gaming concepts in CCM (especially the concept that industrial pollution causes unhappiness).
How do cumulative religions work? The use of my "enhanced Techtree-methode" allows that the same techbox can contain different buildings for different religions (p.e. the techbox Religion contains a basilica for the christians and a mosque for the moslems).
If there are enough cities with temples (3 in CCM),
religious communities of a basic religious tendancy can be formed (for the modders: An era none tech for the given religious tendancy and three temples as additional perequisite to form a special religious community in that city). In CCM there are the following religious communities: The Christian Community, Islamic Community, Buddhistic Community, Hinduistic Community, Hebrew Community and of course the good old bloodcult of mesoamerican civilizations.
When looking on these religious communities, I have a certain tendency to Hinduism

.
If you have such a community in your city, you can construct buildings for them with the proper technologies (p.e. a basilica with the tech "Religion" and a christian community in that city as perequisite). If you have enough communities of the same religion in your civilization, you can form a worldreligion (p.e. with 3 islamic communities as perequisite the Great Wonder "Worldreligion Islam".
If you found such a worldreligion, you not only receive a religious community of that religion in every city you have around the globe, but also the hapiness of all your religious "level 1-buildings" (mosques, basilicas, etc.) is doubled as long as you hold the holy city, where that worldreligion was founded.
If you capture a holy city where another worldreligion was founded, you get enough communities of that worldreligion to additionally build religious buildings and wonders of that religion, too. That civilization now has the possibilty to make other parts of its population happy, that otherwise would be surpressed by a single state religion.
And there are a few "
Crossover Religious Buildings" that are similar important for more than one worldreligion. Par example the "Dome Of The Rock" gives an islamic community all around the world and additionally an hebrew community in every city of the continent, what is mostly enough to build the religious buildings of that religion, too. Other "crossover religious buildings" are the Hagia Sophia, Angkor Wat and the Mesoamerican Christianization (the last one allowing the bloodcult civs to switch to Christianity if they want that). If you catch a holy city containing one of these wonders and you have a third religion as your basic religion, you have access to two more worldreligions.
Of course there are wonders in CCM like the Vatican, the Kaaba, the Potala Palace and so on, boosting level 2 religious buildings (like cathedrals, great mosques, etc.).
Additionally each religion can build its own
special religious units. If your civ has more religions, it can construct more buildings that can autoproduce religious units. As perequisite for building new religious units your civ must be in government Theocracy. There are two kinds of religious units:
a)
Holy men:
Prophets, missionaries, priests, yogis, mullahs (and so on) are autoproduced by special religious small wonders. These units are able to convert other units as monks for their religion and these monks can give a lot of culture to cities of that civ (see the CCM concept "Great cultural persons").
b)
Religious warriors:
There are some religions, which can build small wonders autoproducing special religious warriors. So for example Christian civs can build the Crusade, Islamic civs can build the Jihad and Buddhist civs can build the Monastry of Martial Arts, producing Crusaders, Ansar Warrior and Warrior Monks. Hindu, Hebrew and Mesoamerican civs can´t produce religious warriors, but they have other advantages to compensate this.
The trait religious in CCM is added to every civ to cut down the phases of Anarchy in gameplay and therefore this is no special trait any longer. Some great wonders still have the Religious flag, so Golden Ages triggered by by Great Wonders in CCM are still possible. In CCM you need three triggered traits to receive a Golden Age by wonders.
