I just want to make clear that I have nothing against more diversity in the game. As an European I've always felt the sims offered a very American view of life, so it's really nice to have new worlds like Windenburg and San Myshuno. I was recently in Hong Kong and woooow I could totally see the influence it had on San Myshuno and I loved it.
What I've noticed is that, as usual, the townies the game generates are too random... I like my townies to have a cohesive look, so it would be nice if their appearance matched their supposed ethnicity! I know it is not a huge deal since you can edit their look on CAS. However, it is so time consuming and such a nuisance to me!
