Presumably, that means there will be one
The ESRB has published a rating for The Walking Dead: Game of the Year Edition, indicating that such a product will be making its way to the marketplace soon. The (unsurprising) "M" rating applies to PlayStation 3, Xbox 360, Windows PC and Mac versions of the title.
So often, a "Game of the Year" edition of a game can come with a bit of snickering toward the veracity of such a claim. With The Walking Dead, there is very little room for that. We made the same statement with our award for last year, and it swept up a ton of similar accolades from all over the place.
We'll likely get a proper announcement out of Telltale in the near future, along with already promised information on the second season. I'm curious to know what, if anything, will differentiate the "Game of the Year" edition from the already available season one content. The inclusion of 400 Days seems likely, but hopefully they have a little something else in mind.
