Yeah i have no idea how the game's going to be but the trailer itself is a masterpiece and a stroke of genius, as its the very first game trailer to have made me heartbroken and i can understand peoples criticisms of it. If you watch the normal trailer, i don't find it as heartbreaking as the girl comes back alive, but the reverse is, its really clever on how they did. Also the music helps.
Erm Rodo its sad because of the little girl and what happens to her and what her dad does to her at the end, i know its not real but come on that dosen't move you in anyway?? , its also shocking as normally things like that involving children in any media, certainly in the UK aren't aloud.
