My personal (and falriy strong) feeling is that if the game revolves so strongly around players creating exactly the characters they want to play as, then it's best to protect their "investment" in the game to a degree. It's not that death is impossible, it's that it's treated more as a story element than a game element. I'm aware this won't be a universal opinion, and so there are going to be optional rules for mechanic-based death. It doesn't even have to be that complicated... just removing the "lose your nerve" effect and slap on a dying rule for wound accumulation (dying when your max HP hits zero seems tedious if predictable; rolling a d6 and dying if it's greater than or equal to your total max HP would be a bit more dangerous and suspenseful).The game doesn't have to change much to allow for player death. It'll just likely play a bit differently. How much differently? I'm not actually sure about that, in the absence of playtesting. It's not like every scene is going to be composed of death traps, bottomless pits, and deadly battles.
