Full of american animals? Ehhhh... I can not really agree with that. I wish we had more American animals, in addition to more european animals. As far as I remember we actually have more asian animals in the base game than american.
Agree with you on this. If we go by base game alone, it's more that the game is full of African and Asian animals, with some North American snowflakes. Going by habitat animals only: Four species total, 8 total if you include the Arctic pack. Africa -28 in base game non-deluxe edition, Asia - 18 in base game non-deluxe edition. Europe has 2 in the base game both of which overlap into other continents (Flamingo and Timber Wolf) I'd say at this point North America and Europe both need more representation.
