Ok first of all. Those who understand Saw is not simply a horror movie are good to start off. Saw is a movie which is about a older man willing to help other people by letting them play a game. This may sound cruel for those who know the movie and watch my manner of writing. But everyone knows what I mean. What Jigsaw does is wrong, but his victims should have learnt from it.
In the video game, you control a character, apparently... And I don't see how you can make a video game of this movie. Isn't that kinda pointless? Respect to the video game, but it can not bring forward the same message as the movie does. You control a character, you search for weapons or clues, watch out for traps... Silent Hill?
And after all, maybe I should go to English class more to write properly instead of watching gore movies
