The idea is to combine exploration and functionality with entertainment. For example, the first two pictures show very different settings; consisting of a possibley abandoned artic station to an Earthy romantic tone in the second image, with nature starting to overwhelm the man-made structures. Both are intriguing in their own way, drawing in the audience with a unique sense of wonderment and curiosity, while at the same time knowing they are no the first to step foot there.
This third picture adds a sense of depth to the environment, really provoking the audience and opening their imagination to interpretation of what and where this place is. I know when I was looking at these level designs I started to ask myslef these questions: What is this place? Why is it important? Does it serve a function? And why am I here?
