Looks like I expressed that badly.
I am talking about games where you play worshippers, not gods.
But at the same time, ones that really gets into what it means for religions beliefs to be real.
an example of what I DONT WANT would be DnD. DnD as a game has gods and divine magic, but that fact is almost meaningless in game. You can literally strip the gods from the cleric class and all they are is another kind of wizards. The settings of DnD rarely get into the nitty gritty of what it means that their are gods. Characters don't as a rule collect holy relics, they don't spend time fasting or praying, they don't go on pilgrimages, nor do they make sacrifices.
By contrast, Artesia: Adventures in the Known World actively promotes activities such as ritual cleansing, fasting, sacrifice and the like, and work it all into the way divine magic works. It is not unreasonablecharacter behaviour in a game of artesia, for the PCs to sacrifice a ram, before going on a quest, because it will give them access to divine magic. On top of that, the whole setting is about the clash of cultures and religions, with grand religious wars being faught between sects and/or religions.
So what I am looking for are games that meaningfully explore in theme (or mechanics), polytheistic religion.
