Permanent death is a mechanic not often featured in many games today. But perhaps it should be. These games challenge you like no other, sometimes granting you only one life with which to finish the entirety of the game and if you should die, you have to restart from square one.
There’s a big difference between a game that’s controller smashingly difficult, i.e. Demon’s Souls, and a game that only gives you just one life to play with. It creates an immediate sense of peril, forcing you to ever so carefully tread new territory, not knowing whether your next encounter may be your last.
