I was fascinated by the tomb kings' units. I wanted to import them in Medieval 2, at first as a faction then as units owned by Egypt, or Turks (rising to defend their threatened resting places). I have no intention of publishing the mod, it was for personal fun.
I went through every tutorial, this http://www.twcenter.net/forums/showthread.php?631276 in particular seemed the right one. However I was unable to import any units, clearly I must have missed something would you please please give me a hand maybe listing the files I need to copy? There must be something not mentioned in the tutorial. In any case I can't spawn them so the appear not to be in-game, most sadly.
Or maybe you could consider a spin-off!
