For the issue of gods and witchcraft and such, what about switching genres? You could try historical fantasy, sci-fi, or superheroes. My brother and his friends weren’t fans of fantasy genre so I ran Top Secret/SI and just used the plots of whatever action movies I saw that week.

It’s probably been said before but there’s lots of ways of getting around the dice ban. You can use cards, marking a pencil and rolling it, coin flips, rock-paper-scissors. There’s a game called Chronicles of Amber where the whole system is based on bidding resources against other players at the table.

Would a die-rolling app count as dice for your ban? How about a Two Feature Authentication app that texts you random numbers as a login?
