Sorry for the double post, but
Having the ability of choosing checkpoints, free-saving or whatever escapes permadeath at the beginning of the game IS STILL an option you have! But even if you can do it during mid play I still don't see a problem with it as you are NOT FORCED to use it. Yes you can delete a save-game of any game! Fraks you can play ANY game in the world as permadeath if you want to. What are you trying to say here?
I realized what you're not getting about the objectors here. You say it's okay to have the option not to die (or more generally, not to do whatever happens in the course of playing that they don't like between now and their previous save). It gives players options and options are good.
The problem with what you're suggesting is that it's
not okay. Reloading your save file is cheating. If you give players the option to reload their save file through official, game-sanctioned channels, you're saying it's okay to do that. But it's not.
You can argue all day about how you feel, from a systems design perspective or whatever, a situation where you can circumvent the game's design and save scum anyway is equivalent to offering an in-game mechanism to do so, since, you believe, everyone's doing it anyway (or everyone should be free to, whatever). Well, good luck convincing roguelike fans of that.
And, by the way, it's not equivalent. Roguelikes should be played on third party systems that you don't own, not downloaded to your iPod or whatever. In this situation, you
can't circumvent the game's design and there is an essential difference between providing in-game save file reloading and not doing so, as is the roguelike tradition.
