Completely agree. I don't know why some people are so defensive about this. Next thing, you'll have mono-parental mothers who'll want to be represented, you'll have transsixuals who'll want to be represented. It will never end if we try to represent everyone. There aren't even fat or skinny dudes in any TES game, children are something new and you want gays? Come on. I don't know if there will be families or anything in Skyrim, but the best for Bethesda would be to stick to heterosixual two parents families, no need for them to embark in an endless journey into representing every possible situation. It's a fantasy game anyway, no need to make them too fancy. Who knows, maybe homosixuality doesn't exist in Tamriel, as far as I know Nirn and its people are quite different from Earth. I seriously don't know how not adding them would be detrimental to the game, it's the least of my concerns for any game; I'd rather have everything else to be perfected than Bethesda loose time on something which is not necessary in any way.
Please don't use my post as a quote for fortifying your own opinions that does not reflect my own by leaving out half my post. I hope that you are ironical or something, because twisting my post like that would be enough for reporting it to the mods. Homo/Bi/Trans/sixuality etc can be a touchy subject, and I don't want to be seen as the one critizising when I in fact like the idea of exploring different types of relationships.
Original post:
The thing is, not having it in subtracts something from the game. Being a RPG, the world seems alot less believable if the characters act like if they were part of a Donald Duck comic.
The Elder Scrolls series focuses so much on building the player's character that it often misses out on making good NPCs and relationships between both themselves and the player.
