What I find truly disappointing are the number of people in this thread who are upset (or dissatisfied) with a popular 'youtuber' giving publicity to a high quality game and to an interest in science, physics, or something beyond what may (or may not) be taught in schools. I am appreciative of any form of media which garners interest in science or encourages others to learn more about the world around them. This reminds me of a perfect South Park clip (you have been warned) about smugness and a false sense of elitism.
