Not all the fairskin mods make her that fair (though I've seen the oddity of the platinum blonde ice princess and the flaming haired celt). Some just lighten her up to a couple shades lighter tan brown and change her hair color back to dark auburn. Personally I think she's about Duncan's color now and since his family was also from Rivain, it works. Plus, you know, unrelenting sun on a pirate ship tends to make one a nice toasty color even if one's dark to begin with.
My avatar is the second darkest skin possible in DAO-- see how dark she is? In DAO, Isabela was signficiantly lighter than my Ollhu-- so she wasn't quite that dark.
But Isabela WAS the second darkest skin tone. Her designer confirmed it on these boards after there was an outcry that they suddenly "made her black" in DA2. The lighting in the brothel in DAO made me think she was lighter skinned too, but I'm happy to know that she's actually dark-skinned. Just because we don't often see the primary female love interest in video games be dark skinned.
I don't want to say Isabela's skin color made me love her more, but it's just nice to see non-white characters portrayed as sexy and independent. I also like that she was strong and sexual. Of course, you get a lot of crap from some gamers essentially being sexist about her "sleeping around" when they'd never say that about a guy....
Anyway, I suppose it's fine if people mod the game and the characters how they personally like. But the "Make Isabela White" mods ****** me off on a broader level, with the insinuation that making her white will somehow make her more attractive.
