they do need a fear of death in the game some people just dont care then let them selfs die just to piss people off. but if you turn the tables and make them not want to die.......

people are scared to try new things anyways so adding a fear of death wont cause that to happen.

hard examples:
FFXI = lose xp

everquest = you droped everything on you then you had to go back to the place to get it.
