Think of it from a gameplay perspective, brand new player to ES buys Skyrim cos of OMG I canz keel dragggonnsss??? (<< Actually what made me notice Skyrim in the first place

then I read up some about it, and yeah, I'm hooked. I thought of myself as more of an action adventure/racing type player (GTA, Saints Row, Red Dead, Forza, Driver, Test Drive etc etc), but yeah, skyrim just has that special something that I can't explain)
Aaaaanyway sorry for that, tends to happen, it's happening now as I type.... I digress
New ES player, loaded it up for the first time, takes a nice looking Nord female, gets in-game and the first thing that happens is Ralof tells you to hurry into the keep and stay there til the threat is gone. Very different game indeed if they cared about sixuality.
That's just gameplay wise, it would svck to play a female if all they could do was get married, clean up, cook and sweep the floors.
