[Deathstalker]

Personally (and everyone does it a different way) I just put 'old' in front of the original file, and then add the new one in. But that is just for 'one shot' changes, ie, the modd I have is just the CompEnhancement.txt(sp?) so you don't need to create another whole 'Data' directory and a new path.txt. Then when you need the original file back again just put a '1' or something in the name of the modded file and take the other pre-fix out of the old file. Time consuming but that is how I do it.

And yes I would definitly use the TDM modpack for AI's if they are added, my one wish for PBW though is to have every race available (hard task I know...)...But it could be done, just have a central TDM-Modpack file and then add in all the uploaded races, that way people could add the races they want to the game.
