Permalife games are difficult in an entirely different way than games requiring skill or strategy, requiring players to enact the motions of continuing existence, even in the face of survival under (or complicity with) the evils of that existence.
OUTLANDISH: Permalife is not difficult. If the player is always alive, there are no stakes and nothing to lose. The player's instincts to run if they are seen or fight back or hide are completely neutralized. This does not benefit the player in any way. There is nothing to deal with in the face of survival because survival is guaranteed.
