Welcome to the profile of Rin.
I'm an Australian here to wreak little havoc in the world of SS.
As a person I'm friendly to a degree of which I can seem to be extremely blunt and sometimes a tad rude, I don't mean most of the things I say and probably shouldn't be taken to heart. I can be extrmely lazy and I find it hard to actually do things for other people when it's requested.
As a past time I do enjoy games, I mostly play on the PC rather than other consols but do play a lot of consol games too. I also like to watch TV shows / anime and some movies.
Here's a list of games I play;
Online; Flight Rising, Howrse, DragCave, DragonFable
PC; The Elder Scrolls V: Skyrim, Audiosurf, DragonAge, Imagine Champion Riders, Age of Empires/Mythology, WarcraftIII
xBox360; Red Dead Redemption, Elder Scrolls V: Skyrim, Left 4 Dead, Assassin's Creed, Darksiders, Devil May Cry, Skylanders, Legend of the Guardians: The Owls of Ga'Hoole

I'm a firm believer in realistic characters.

Breeds within the alotted era; I find this to be a rather large issue. For example there was no Kiger Mustangs in the era of spirit, they weren't discovered until 100 years after the events that transpired. Another great example would be the lack of actual Quarter Horses, these horses were once called "Steel Dusts."

Families of the main characters; As much as this is hard to believe... These characters share a bit of unrealism. It's going to be unlikely that these characters have super secret lost siblings. The case with shows like Lady and the Tramp and 101 Dalmations is clearly plausible, these dogs were actually bought from breeders/shelters, however in the case of Little Foot or Spirit the likely hood is low, Spirit COULD have a long lost sibling but by the looks of it the sibling would probably be older.

Offspring is a hard one to explain in this case... The amount of children one animal can have is actually limited. A lion won't come into heat while she still has a cub around, the only option in the case of a female lion can come back into heat for a new litter would be to kill off her current offspring, grizzley, isn't it? Another example is puppy farms and horses. Dogs can only breed so much before she becomes useless, it is safer to give her at least a year before her next batch of puppies, same can be said of horses (though two years is a lot safer in their case)

Genetics are rather annoying to talk about, but here goes; the offspring won't adapt their parents exact markings and / or shape! Infact, depending on what you're breeding the offspring can turn out to be entirely different from BOTH their parents, a perfect example would be Spirit; his dam, Ezperanza is a palomino mare with markings on her legs, his sire, Strider was a plain old black with no markings. Spirit came out as a counter-shaded buckskin with no markings. The two genes of the horses acted upon Spirits coat to make him a buckskin.

Last and formost for the moment is FCxCC or CCxFC. "New mates" of certain characters don't really play out to the canon of the franchise unless it is played well enough which is very rarely is. Tramp might be a bit of a ladies man but he has since been loyal to Lady. It is possible to do offspring of Tramp before meeting with Lady but otherwise not going play well post Lady. Simba and Spirit have rights, as alpha males of their pride/herd to choose whichever female to mate to, it would be the same if a rival stallion took over Spirits herd.
