I have this idea for a mod where you can make a 4th race. I can't do this because I just can't mod. Here's how I thought you could do it. You take a building from a race and set it so it can build a type of unit which you then give the ability to mine and build. And then so on and so forth. You'd probably have to modify the sprites to make it seem realistic. I'd like to know if anyone likes this idea and would be willing to try and tackle it.
