Just like with Prime, Dread's beauty is not the realism of its graphics but the cohesive and haunting atmosphere that is being conveyed. You truly get a sense of solitude and the unknown just by staring into these vistas. The graphics are not about photo-realism, but rather they are about making you feel like you are looking into a fully cohesive world. Every painstaking detail in the level design is thought out and given meaning and relevance. There is no suspension of disbelief necessary because like it feels like everything that you see has a history and fits seamlessly with the back story of the game.
One of the things that I Ioved most about Prime 1 was that even the equipment power-ups that you found during gameplay were completely justified in the backstory. For example, in Prime 1, it is explained that the Chozo left these items for Samus because their prophecy predicted that Samus would one day come to destroy the evil. I have not played Dread but just by watching this video, I can feel a lot of this same cohesiveness that allows you to forget that you are playing a game.
