This game will be a solid 10/10 no doubt about it. :/
Although, the length of the game could be a big downfall for it. They are saying it will take 8 to 10 hrs to complete in order to remain scary and not get repetitive. I can imagine speed runs popping up on YouTube not long after launch completing the game iridiculously fast. I just hope they have some kind of bonus levels unlock once you complete the game, or at least an alternate game mode or something... something that doesn't fit in with the storyline or doesn't depend on the scare factor.
