@yoav_r did this ranking a couple of months ago, but now that we have two more packs, I feel like a new pack ranking discussion is due. Here's my updated ranking;
10: Arctic Pack - With a mediocre animal selection (where's the Musk Ox and Walrus?), a niche building theme, and no exhibit animal, this was an easy pick for last place.
9: Africa Pack - Had this been an animal pack, I would have placed this much higher, as there's so many African animals this game needs. The building theme is fine, but the fact that we needed to wait for a DLC to get the White Rhinoceros and Meerkat speaks for itself.
8: Europe Pack - Not a bad DLC by any stretch of the imagination, but European animals don't interest me all that much. The building pieces are still good though.
7: Australia Pack - A good animal selection, a good building theme, and good foliage. This is a perfectly middle of the pack DLC.
6: Conservation Pack - A bit too Asia-focused for my liking, but it still has a strong animal roster, with every species being highly requested, even the exhibit species. And who can forget those backstage pieces? A very crowd pleasing pack overall.
5: Southeast Asia Animal Pack - Despite the inaccuracies of the Malayan Tapir, this pack still boasts a strong animal selection with a good mixture of well-known animals like the Sun Bear and Clouded Leopard and obscure ones like the Binturong.
4: South America Pack - This one surprised me. The animal selection is surprisingly good, though not perfect, and the building pieces are excellent. Love me some bamboo walls.
3: Aquatic Pack - The addition of deep diving animals opens up so many possibilities for habitat builds, and the building pieces are surprisingly versatile.
2: Wetlands Animal Pack - It's basically the Aquatic Animal Pack. This pack has a very diverse selection of animals, with every continent except Antarctica having at least one new addition, and all of them are beautifully made.
1: North America Animal Pack - A near-flawless selection of animals from a continent that desperately needed some more additions, and this pack contains some of the highest quality animals this game has ever seen.
