I had a hunch this pack would have wonders and a new map. The wonders look cool I like having an earlier way to boost marshes. Wetlands also looks fun. Obviously it'd make most civs struggle more but I think that means a distinct play experience which is what I want in map scripts.
Portugal and zombie mode I don't care much about. Maybe they'll have interesting civ abilities. I liked the other 7 civs and all the other modes (except apocalypse) so I'd say NFP has been an overall great expac for me
