Add A race?

I donno if this is possible. I got some certain .txt files and I see that the deamons have all the stuff to be a seperate race (workers, buildings, etc.) I still don't have the retail version (soon I hope) but Is it possible to ADD a race and not REPLACE a race. If so tell me how. I already know how to create units and all and now I am just waiting for retail to get my ideas togather.

Blizz said that demons were supposed to be a full race, but instead they took them out and made them super-extra-unimaginable-extremely-powerful. they should have all that is needed for a regular race.....

Yes, it is possible. Just create new custom buildings and units, and with the buildings, give them new unit creation abilities, and make a peon-type unit able to build the new custom buildings. That's the simple way to describe it.

I am working on a mod that adds 4 new races, each very unique. I started with the beta version, but after dealing with WE beta bugs and seeing the retail, I realized that we should all wait until we get the retail to do heavy modding, like this.

Custom buildings/units would be map specific. You're gonna have to do spell editing/modification (you can't really do unit summoning tricks cuz you need those to still work with other races, and even if you made player specific the icon wouldn't look right). Adding new races is gonna work best on the slk/mpq level :p
