Anyways, what I was saying is you are actually over simplifying my thoughts, not only are HP modified but also armour, damage, tohit chances. So not only do you have a rate that now deals out 20 damage instead of 10, he also had a 60% chance to hit you vs 30%, and you have a 40% chance to hit him vs your old 80%. You can also make traps and locks harder too, but with a certain cap obviously.
I understood your point. I was just saying that the effective experience for the player when a game is scaled that way it that the higher difficulty settings are more tedious, rather than more difficult.
As Randomizer says, I could and would do exactly what I do with Spiderweb Games and only play them on Normal difficulty.
I just think there are better ways to scale the game. Perhaps rather than changing anything about the statistics around the game, there's a simple X factor in every calculation that is adjusted out of the player's favor as you make the setting more difficult. That would run across all possibilities in the game (from fights to picking locks to random loot).
I'd still opt for the Normal setting, of course, so it wouldn't matter to me.
