This follows on from my discussion yesterday regarding permadeath.
I was reading some forums on that very subject and someone mentioned that all MMOs already have a permadeath option.
It's called deleting your character.
If you're so keen on permadeath, then when your character bites it for the first time, don't resurrect - simply logout, delete char, type in the confirmation code and reroll.
I suspect that people who are very keen on permadeath as a game function like it that way in part because, if given the option, they will rez their character like everybody else. They want their hand to be forced so they don't have to resist temptation.
But what I suspect it really hinges on is creating obstacles for other players. They would argue that permanent death gives more meaning to quests, more risk. This is true.
It's also what would worry me most about such a system. Online games aren't known for their level-headed communities. Instituting permadeath is basically ceding emotional resonance to the griefers.
So remember: If it's that fucking important to you, delete your character the first time you die. If you can't bring yourself to do it, then never again make a bad faith argument about how much more exciting it is to risk it all to server lag, trained mobs, and overpowered bosses.
