What races are evil?
from
GalCiv2 Forums
I can't find any information in game about which races are evil and which are good or in between.
So far, I can only tell that the Drengin and the Yor are evil, and the Altarians and the little-green-guys-that-look-like-ET are good.
I guess the Arcean and the Drath are neutral, but I can't tell any of the others.
