NoThick paper and nice printing quality. My son loves this.I didn't actually realize this had something to do with some sort of game until I looked at the bottom of the poster, but it's a great solar system map. It has a fun, almost cartoon-ish design, and includes all of the major moons very roughly to scale, even though of course the map itself isn't to scale. I also love that it depicts the planets actually circling around the sun, as opposed to a straight line. It reminds you how much time of year affects the distances between planets. It also includes TNOs like Makemake, Haumea, and Eris.My nephew is obsessed with space and he loved this poster! We got him a poster frame and hung it in his room.
