That doesn't change the fact that unrealistic choices have been in the game from the start.
Oh yeah, they are both unrealistic. The main concern behind my preference against animals that do not do well in captivity is about the animal welfare message behind it. Otherwise, animals not breeding in captivity in real life readily breeding in the game is also not realistic.
The difference here is welfare related, which places the three-toed sloth in a different group with indri, Javan rhino, and so on, instead of animals that don't breed in captivity. Now I understand why we couldn't agree to disagree. We were discussing different concepts.
