I never cared about "LEAKED CONTENTS" honestly if it was such a bad thing whoever leaked the information would get fired from their job but honestly I think it's a marketing ploy to make impatient gamers think "Oooo they "leaked" this part of the game so it must be good". There for I simply ignore everything that's leaked.
It's not a good idea to only rely on marketing material to decide whether to buy a game or not, since they only show you the good parts. You need some other information to get the full picture, whether that is leaked before release or by just waiting until after release to get some real non-paid opinions.
