Guild Wars 2

PopeUrban.2578:

My only real question:

Why would you even want this?

These aren’t just genetic offshoots of the same species. A sylvari, charr, and human are more different from each other than a housefly, bonobo chimpanzee, and tyrannosaurus rex.

These aren’t halfbreeds you’re talking about. These would be abominations born from morally questionable acts akin to beastiality

In game my human character is great friends with a number of norn, charr, and asura. In real life I am great friends with a number of dogs, cats, and horses.

I have not once found the act of having those kind of relations with my animal friends even remotely appealing because it’s really gross

Similarly, I’d imagine even the basic concept is extremely distasteful at a core instinctual level to the sentient races of tyria.

Beastiality is considered extremely distasteful by most humans. that doesn’t mean there aren’t any outliers that still engage in it anyway.
Furthermore considering the hypothetical scenario of romance between two members of different species in GW2 presumably involves consent between two individuals of comparable capabilities to think I’d say it’s rather less immoral, if at all, than beastiality would be.
I’d think these would be the reasons why you would want to discuss whether or not it’d be possible and then come to the conclusion it wouldn’t be possible (aside from the hypothetical sylvari mimics that aren’t actually halfbreeds) to have halfbreeds, for various reasons mentioned by other people.
