Ninja Theory’s Project: Mara will be a psychological horror set in a photorealistic space, which is probably going to make it a whole lot more terrifying when something goes wrong. The game is set in a single location with a single character, and in the latest developer diary, you can see the kind of meticulous care that has gone into recreating a space and keeping it looking photorealistic.
Between ultra-close photography, scanning samples of materials in varying light conditions, LIDAR scans of the entire apartment and more, Ninja Theory also had to build a whole host of new tools to recreate the apartment in such photorealistic detail.
The in-engine shots look amazing, but I have no idea what kind of hardware you would need to have games looking like that. Also, I am not sure how well the technology would scale up for having this level of detail in any game that doesn’t have such a small, finite space to take place in.
