i'd actually been thinking recently that a toggle button on temples could let the player worship a particular god, perhaps similar to the idea that Wonders have toggle abilities that will affect the territorial influence of the player, their allies, or their enemies. for example, the various Hellenes could choose to worship Athena for a while, which improves the rate at which buildings are constructed and repaired (though best known as the goddess of wisdom, she was also the goddess of architecture), and then after a while they switch over to worship Ares to give their soldiers a boost in combat. in the case of factions with a shared religion (like the Hellenes), it would probably be best to pick two or three gods which are given to all of them and then another which is more unique to their culture or embodies what they did historically. for example, only the Athenians would be able to worship Athena. i would also recommend this only in the sense of how that god can accurately apply to a game without any other mythological influences. for example, while Zeus immediately jumps to mind as a Greek god, i would actually suggest that he not be one of the Olympians that can be worshipped, because he embodies much more nature-oriented aspects than some of the others, as opposed to aspects of humanity like Athena does, for instance. in contrast, Poseidon would work well because, as both the god of the sea and the lord of horses, he has a wider applicable range to us mortals: he could improve the rate at which cavalry are trained and make it so that ships move faster, giving them safer passage across the sea i'll try to write up something about which gods could be applicable to all this; one of the benefits of working on a mythology RTS project as well is that i already have alot of ideas
