I'm tempted to reduce the options a little to simply things. Like if you choose Kingdom it preselects all the kingdom techs, people, selects good, etc. What do you think?
Also, I just created a race with some strange colors, despite the in-game editor not using the skin color, building color, roof color, you can indeed use them and they show up.
However, the attributes on the last tab (like assasin, etc.) don't really work for races. I am trying to determine what will actually work and what won't so stay tuned for that.
