I used it to make a Bajoran/Cardassian half breed. Also, I made pretty much identical human races because I like the diversity of being able to pick my own racial traits. Some humans are just bad leaders. Also, I found the sliders to be a little limiting in creating really iconic, unique faces when you're choosing a premade race. When you select Alien, the slider limits are expanded, and you can create some very nice looking variations of the human face that aren't possible with the sliders where they are presently.
