I'm trying to find the file that controls what the race says when you go to pick your race and can't find it. I would like to change Orc to Naga for exsample.
It's in the Game Interface area under the Advanced tab.
Unfortunately, it won't work right away. You have to play the game once, then the next game will show the custom races.
You can also change the name by editing globalstrings.fdf, but that only works if you load a custom MPQ containing the edited file, so it's fine for something like a custom single-player campaign or if you plan on using SEMPQ anyway.
