This statement is somewhat false. The game DOES differentiate between family and non-family via the inbreeding mechanic. If you compare mates, there will be warnings next to any animal the animal is related to. Considering the game DOES distinguish family from non-family, it really isn't that much of a stretch to include a few lines of code in wolf behavior that says family = friendly, do not fight, and stranger = hostile.With wolves specifically it is the case that they will fight when you put another wolf in the enclosure of an established pair.
So it makes sense if you consider wolf behavior regarding "unrelated" individuals.
The game AI has currently no function to differentiate between family-related and unrelated individuals.
Nor does it have a function to consider the time it takes to form a pack.
So this does cost a lot of extra work and changes to the AI-system.
They already announced that they are working on the AI(more positive behaviors etc.), but it will take time.
All they really have to do is remove the hard group limit on wolves, so that they do not fight due to ""overcrowding"", specifically, and instead add a behavior clause that states if there are more than 2 wolves in a habitat, or in the case of 2, both are same sex, the wolves will begin to fight any wolf not family related, regardless of sex.(i.e. 'alpha female' can attack a stranger male, instead of the male having to do it, but if the only 2 wolves in a habitat are male and unrelated they will fight.)
...Also, the alpha system needs to be completely removed from wolves entirely because it was proven to be false by the exact same scientist who came up with it, and wolves raised in a proper and non-artificial pack(i.e. family group, not a bunch of unrelated wolves thrown together) absolutely do not fight for dominance at all whatsoever, this has been repeatedly observed by researchers and scientists observing wolf packs for years in the wild.
I can understand keeping the ""alpha tag"" as an identifier of the main breeding pair, just so that the rest of the pack cannot breed unless the breeding pair is replaced, but the whole "fighting for alpha" thing needs to go.
They could also just make it so that wolves will not inbreed, period, because wolves don't actually inbreed. It's instinctive. Wolves will not mate within the pack they are born into, therefore even without alpha tag they could make it so that wolves simply don't inbreed and thus only the parents, the main breeding pair, will continue to breed.
