Polygon has as a nice article on one of the Destiny-related talks given at GDC this year. David Helsby, Destiny's Senior Animator, went in-depth on how the first-person animations were created to be smooth but realistic, and at the same time, not induce motion sickness in the player. Interesting read! VG24/7 also has an article on the talk. Thanks CruelLEGACY.
