      Additional note by Ghost: They are made by cloning the Science career. Therefore it will look like Science. And it will overwrite the original science career if you do not change the GUID. If you want to edit another Maxis career, you can go into advanced mode and clone the career you want to work with in Object Workshop. Of course, you will still need to change the GUID if you don't want the new one to overwrite the old one.
