Full hour and twelve minutes worth. This is my first time seeing a solid chunk of gameplay. Was debating whether or not to go in blind, but eventually caved. Gotta say game is looking great. Menus look slick. Character models look really good. Feel a huge desire to just start exploring the world(s) and leveling a class. Can't wait to get my hands on the alpha or beta. Let alone the full game. Ya did good Bungie. My hype feels justified. I'm actually kinda worried about how I'm going allocate time to play other games now. :P
