The Norsca expansion is pretty much exactly what it says on the tin. The beast hunts are a nice and interesting way to deviate from the traditional building and recruitment structures, while the mechanics of the four gods is very distinct and allow for some potentially interesting choices and decisions to be made. However, it likely won't persuade anyone outside of the franchise to join in, and is pretty obvious in both what it provides and what said provision will do.
