The new religions are an interesting touch. At first glance it seems like the default Atheism is a pretty good one to start with since you can passively increase your Willpower to 80 with it. After you get to that point I would probably want to switch to something else. The combat damage bonus from Aesir looks the most interesting to me but if combat isn't your thing some of the others have some interesting bonuses as well. Looking forward to playing around with it.
