I use the club system and the calendar to make religions in my game if I want them. There’s a tradition on the calendar if you have Seasons called attend holiday ceremony that’s a rabbit hole, there’s also a charitable works rabbit hole on the phone that I think came with Parenthood that I incorporate as well. Then I build churches I set as museums and use those for club hangouts with activities like read books, play organ, sing, give speeches etc. I can set up religious rules through the club forbidden activities and rivalries with other religions using be mean to as a club activity too.
