Pft. Dark Souls and Demon's Souls were loved for their difficulty.
I just have to say.
I was playing Dark Souls - I've barely started, only just met the merchant with the katana...and killed him. I didn't mean to, I swear, but I pressed a wrong button...and he went for me, so I had to sock him one.
Anyway. I found out that, in order to kick, I had to hold my weapon with both hands, and hit the left bumper and flick the left stick forward simultaneously. At this point, I thought, pah, this isn't going to work. But at least it'll be the game's fault, and not mine.
It worked perfectly. Every time. Theoretically, if I wasn't such a dick, I could have won easily. But my fingers got confused by the notion of actually doing something right, and in the end I rolled about, drank all my estus and killed the spearmen with my face.
And I had nobody but myself to blame. And I still quite like Dark Souls. So what does that tell you?
