My least favorite packa from most to least disliked:
1. Barnyard: since this one is an animal, despite having some cool building pieces, i judge it based on that. I never wanted an all domestics pack to begin with but even this one felt short of what i would've enjoyed from such a pack because of the poor animal selection. Alpaca, chicken and sheep are probably the only animals i like in this pack and even then the alpaca feels kind of redudant, but they are all three really well done. Donkey and pig are among the worst choices they could've mase for this roster when a duck and a rabbit or even pony were so much better options. Then there is the dissapointment there is the highland cow in terms of quality. It was probably the only domestic animal i actively wanted and turned out to be the worst of the pack, almost unusable for me. And i really can't believe the goat is not a dwarf goat.
2. Zookeeper's: i mean... Is fine i guess... Overall community favorites almost in every pick but almost none of them were a priority or urgent to get for me (with the exception of the markhor and maybe the Palla's cat, but still not really priorities, they just were in my wishlist). The dik dik turned out to be may favorite animal in the pack. The baboon could look better imo, the bear wasn't really what SA needs and i still don't understand why the sifaka (a hard animal to animate that was done half way instead of giving us what most of us really wanted: another new world monkey, that would have been easier to animate as well). I guess some pieces are usefull but really the scenery wasn't that exciting either and the lack of foliage is sad. It didn't really feel like a celebratory pack at all despite the theming and i'm glad is not the last one because i didn't felt any excitement for it.
3. Arctic: it was the first DLC so is kind of unfair to compare it to newer ones, specially in terms of animal quality, but once again the selection was very perplexing to me. A wolf subspecies that people only like because is a timber wolf kind of remake so they give them an okaish wolf ot use. A really underwelming and cartoonized reindeer and polar bear with impossible space requirements (although not really a problem for me since i only play sandbox). I love the dall sheep but really a musk ox would've been more iconic of the arctic (and the wolf should've been the arctic fox from the get go). The wood aet is nice, but a lot of the pieces are heavely themed and are not flexicolor so that reduces the versatility for me, but i still like them though.
4. Twilight: alright, this one is another pack i don't care much about most of the animals but it gave us our first flying animals (and they were bats which was awesome) and aome very useful building pieces (although some others that are too themed to be useful for the most part for me). The raccoon has grown on me a lot because i think they ar every well done and are super entertaining but i was kind of against their inclusion at that time hehe now i'm ok with almost all the animals individually but as a complete roster i don't think any of them are really that exciting.
5. Arid: this one is weird because some of it's wrong were corrected by Zookeeper's pack with the addition of the baboon and the tortoise, but still feels like too many ungulates despite a lot of those animals being personal favorites of mine (rhino, dromedary, addax, porcupine). The dama gazelle is beautiful but really if we never got it i don't think it would have ever made my personal wishlist. Similar thing with the sand cat (although less quality than the gazelle). But the main issue with this pack is the missbranding... Is a north african/middle east animal pack not a biome pack. It was our desert pack yet completly focus on Africa and with nothing from Australia, North or South America which was a shame and the game hasn't compensated for that yet since an australian monitor lizard, patagonian fauna and NA desert animals are still missing from the roster.
