I actually don't want any new playable races until the existing races have their options expanded. By that, however, I mean expanded in a reasonable manner - they don't need to suddenly get all sorts of weird traits. We just need new base faces and a variety of new scars/facial features. I'd happily play a male Highlander, for example, if they could have proper eyebrows and had more classically handsome facial options.

One of the biggest issues with new playable races is that every piece of gear in the game needs to be adjusted to fit them. I'd rather see that development time spent elsewhere.
