Except Dark Souls is only "hard" in the sense that it limits the player, instead of actually being difficult for the average player like, say, ArmA 2 multiplayer.

I'd say it's more knowledge than skill based though, I mean you need skill to play it but when you know what the fucks going on it gets much easier!

And that is why the learning curve is so great. You actually have to see an enemy, pay attention to everything it could possibly throw at you, and plan ahead. You can't just breeze through the game just because you have "skill." You have to play it carefully and pay attention, and many people don't like it because of that.

But it was a curve for skill and not knowledge? I think the skill level goes down as you learn more (Not saying it's easy in any way) I personally love the fact it does this and that's why it's one of the best games ever

I suppose so, you win.

Not to say knowledge isn't a kind of skill you acquire from using other skills in the game, so you could also look at needing multiple lines!

I think you may actually be on to something here.

Dark Souls just goes straight up.

And then you hit Ornstein & Smough, and it does a backflip and a loop-the-loop before going off the charts.
