Don't know what the thinking in Hollywood is here, but they're going to make a movie of this game. Loved the game's overall plot and story pacing, but once you solve it there's no way to make the ending a surprise again. That kind of limits the replay value, but it's a beautiful game to simply watch.
However, I've heard that they've got a sequel in the works. And now a movie. Stories are crossing over into all kinds of venues, then making their way back to traditional forms.
With the Mature rating, the game was a strictly enforced 17+ purchase. Definitely gonna be an R rating at the theater too. Still, it would be interesting to see how the game and movie vision are the same/different.
