Stay mad, what is it with people with Kiwi avatars and EBB love and Saiga hate? I've seen two already.
They are very much realistic lovers that don't want other people to have fun or something.
You say ‘realistic lovers’ like it’s a bad thing

there’s different ways to play the game other than yours and that’s fine.
I for one am a realism lover, but I like the oddball every now and again. The only one I can’t stand is when they take the place of a much better option, example:
HBB -> EBB
Brown Throated Sloth -> Two Toed Sloth
The Saiga and Proboscis Monkey, I stand by, are good additions. The Proboscis Monkey not so much personally, but if it makes others very happy, who am I to judge.
The reason we want the Eurasian Brown Bear is because it is a MASSIVE part of European culture, it is a staple of European wildlife and features in SO MANY European Zoos. Yes, it’s a realism argument, but that doesn’t make it invalid. I can understand why it’s not such high priority and that’s fine - I’m not clamouring for it immediately. But I would love its inclusion one day, as free anniversary content or as an easy filler species.
