i have a question about your system. As it is written, i'm not sure that only the players roll dices , and are wounded, stressed according to the reesults (as teh ennemies have opportunities to 'harm' them), or do PC and GM take turns ?
The first seems more probable (as there is a rule about the 'level' of success to have to solve a 'problem'), but i'd prefer to ask your view about your own game .
