Rose giving may not be a part of the wild, but I will play as I chose, and you may do the same. Some sim games I have seen also do not allow stallions to share territories. In the colder months, rarely, stallions will cimbine their harems, though one is usually dominant over the other. Wild horses, truly, such as mustangs and brumbies do not even have territories. They are free-range animals, which means they travel over wide distances.
Mares also lead the harem or herd.
Stallions bring up the rear of the herd, while the rest of the herd follows the lead mare, the dominant mare in the herd. The role of the stallion is mainly to protect and be a mate to his mares. In Dreamscape, we use love as a bond between the equines mainly. Other games use the ways of the wild. Dreamscape Meadows is an escape from reality mostly.
