Thanks so much for that very detailed answer Implode.
I have half of the graphics for a goblin spearman unit so far as a recoloration and adjustment of the halflings to get me started with a relatively easy one. After the first one and figuring out a few things with my graphics program, this is faster than I thought it would be. First one was like 45 minutes, then 2-3 for each of the others.
I also see what you mean in terms of the editor - I went straight to the graphics without looking at it, but I see now how to do virtually everything stats wise. It also reminded me that I need graphics for workers, farmers, and rebels for any race.
One more question for now: would it be foolish to make stats in the XML editor at this point? Will new releases of MOM IME negate that work, or does this not work that way?
In any case, I'll do a little to test the graphics out. I'll change the Orcs to look like goblins briefly. The first milestone will be getting a unit to show in game. The moment that happens, I'll post a link to an image here.
