All I can say is, whatever setting you choose: The fewer stats and maths involved, the better your chances are getting people to play, I think.
I understand that some are married to the idea of dice rolling and creating some randomness and tension into the game that way. But it turns people off. :/
I wouldn't call myself "married to it" but it is kinda my go-to. I mean, I'm trying to think of something else, but I'm coming up empty so far...
