Reflecting on the whole experience, which I did truly love, I don't think Miyazaki was being entirely honest when he said anyone can beat Dark Souls with patience and dedication. I beat Demon's Souls twice, and like that game, I was only able to finish Dark Souls with the help of a wiki for information about weapon damage and such. The final boss was totally manageable because of my very very powerful equipment (+9 Elite Knight and a +5 Black Knight Shield), though I do believe that, quite frankly, I'm kind of better at this gameplay than those people who are really struggling, because of my prior experience with the Souls series. Brad and Patrick will never finish Dark Souls if they're tripped up by the Taurus Demon or Havel (who I thought was a mere trifle - just take your equipment off and stab him in the back: like some later enemies, he's balanced to be very slow and very hard-hitting.)
This is probably my new favorite game of all time, though I understand why anyone may hate it. In recent memory, there has not been one single game that the average person could not see through whatsoever, from title screen to credits, until Dark Souls rolled around, and even I was highly challenged by some later enemies and boss fights, with the advantage of a fantastic online community (/v/, who worships any game designed to be contrarian and obscure) to encourage me on and the incomplete wikis to help me along. Subtracting thirty or so hours for mucking around in PvP and Titanite/soul farming, I'd say that my path through the game was around seventy hours long.
Literally noone can put that time into a game, aside from privileged teenagers (me!) and obsessive reviewers (Gamespot's Kevin VanOrd!), but I think, as a kind of encouragement to all the maybe-enjoying-it Vinnys of the world, it'd be best to just show you my Dragon Man.
