I might give it another go. We will have to decide what the first scoop would be, ie how much of the game mechanics to put in the framwork. I woulld think that movement would have to be left out to start, since it is rather loosely defined in the raw.
Start with char basics , ca, sr, hp, hitlocations, weapon styles etc.
Hm must look in to maptool again, i did look at some d100 frameworks, but ca,sr demands some remodelling.
