Pixels or Death's Ben Chapman discusses permadeath in games, and why he'd like to see more of it:
"Once you’ve taken up the challenge, there’s no bigger consequence. You risk losing it all, hours of work, at the mercy of one bad call or a random fluke. All your effort and enthusiasm and empathy are no longer spread across particular moments, but all come down to that one singular character. His or her fate is now your own too and, from that, the distance between player and character is that much shorter."
