As someone who's never played the game, being a member of the PC Master Race

and long out of touch with Sony, I have a hard time seeing how they could 'get it wrong'. I know the general premise of the games, and I'm sure the nuances of the story are good but while the mushroom zombies are new angle this is hardly an original plot/premise that's been done many times in Film/TV - grizzled father figure leading a child through the aftermath of some apocalypse. With a top tier budget and good well known actors I'm sure it will do just fine, with or without 'gamers'. HBO has a built in audience so they just put this on the front page as their next big thing and people will check it out.
