I know that this most likely has been posted about a million times before, but I wonder how likely it will be for the ability to play against self-made races to be ever implemented. It wouldn't have to be too fancy, meaning a static leader pic could replace the diplo animations and all selfmade races could use just one neutral AI-set. This would certainly make for much more variance in the game as one does not have the classical roles of the traditional opponents.
Is there any possibility that this might be implemented eventually?
