This argument makes no sense. Race and cultural norms are very different issues. Also, the status of women and gays has been established in the DA lore. Throwing in a bunch of asian NPC's requires either a simple reskinning that would be jolting, given we've seen nothing of them in previous games or literature, or a serious dig into what "being asian" means in this world, where they come from, what is their culture? How do they fit in with the rest? If it is taken place in a world based on Europe- which it obviously is it would make no sense. It would be just political correctness- we're doing this to put it in, but it has no real value, meaning, or significance.
Also, please don't put words in my mouth. I did not say Jade Empire means no other game needs to include asians. Please do, create game that explore non-european cultures. I would love to play them, and when I do I won't demand that they have a percentage of white folks in them.
Looks the same to me: making Thedas a littles more "unrealistic" (or simply a little less medieval Europe) if that's what it takes to be more inclusive. And I'd absolutelly support it. And yes, I'd mean to make changes, that was exactly my point, why wasn't it done this way from the start, like it was done with women and non hetersoexual relationships? By the way, I find it hard to believe that if you run into some NPC that look east-asian but that's no different from any other orlesian in any other aspect people would go "oh my god, where did he/she come from?". Like it's already been said, I think most people would not care the least. Are you expecting an elaborate explanation on why is not Vivienne white, in fact?
Also, I don't understand why are you equating ethnicity with nationality and nationality with a culturally homogeneous population. But even if we were talking about cultural and not racial diversity, I'd still be ok with it, maybe ti's true that medieval fantasy revolves around european history too much. But I don't see why non-european medieval elements should be put in different games, why couln't t they be mixed... I admit though that this could take a lot of effort, in DA case, for instance, it'd mean big changes. Simply adding more non white characters, in the other hand, seems quite easy.
